¿Qué es
Internet?
Internet es una red global de equipos informáticos que se comunican
mediante un lenguaje común. Al conectarse a este sitio Web se ha
conectado a Internet. Es similar al sistema de teléfonos internacional:
nadie posee ni controla todo el conjunto, pero está conectado de forma
que funcione como una gran red. Más de treinta millones de personas
tienen acceso a Internet mediante el correo electrónico. Esto le incluye
a usted.
¿Qué es World Wide Web www?
World Wide Web es un término que se utiliza para describir toda la
información y el contenido multimedia disponible en Internet. Para tener
acceso a esta información se utiliza una aplicación llamada explorador
de la Web. El Explorador de Internet de Microsoft es una herramienta de
este tipo. El Explorador permite buscar, localizar, ver y transferir
información en Internet. El "hipertexto" permite desplazarse fácilmente
por el Web. Al utilizar el formato de archivos "HTML" (Hypertext markup
language), el "hipertexto" permite saltar (mediante un hipervínculo) de
una página de Web a otras; dichas páginas pueden contener imágenes,
películas, sonidos, gráficos en 3D, prácticamente cualquier cosa. Las
páginas y archivos pueden estar situados en cualquier lugar de Internet.
Los "hipervínculos" son los entramados de conexión que conforman World
Wide Web. Al conectarse al Web, tiene igual acceso a información en
cualquier lugar del mundo; sin restricciones o costos de "larga
distancia". Acabo de entrar en Internet.
El 30 de abril del 2003 se cumplieron diez años desde que el CERN, con
sede en Ginebra, anunciara el acceso libre a esta red telemática,
conocida en internet por las siglas www y que permite la navegación
virtual.
Con el paso de los años, la World Wide Web se expandió por el mundo
asociando el hipertexto e Internet para facilitar el acceso y la
utilización de la Red a un amplio público.
La idea de la Red se remonta a marzo de 1989, cuando un ingeniero
informático del CERN, Tim Berners Lee, "propuso un sistema de gestión
descentralizado de la información" destinado a la comunidad de físicos,
ha recordado esta institución científica en un comunicado.
En esta experiencia colaboraron varios centenares de científicos de todo
el mundo, que estaban listos y deseosos de acoger una nueva manera de
intercambiar información a través de la Red Internet.
A finales de 1990, la idea de Berners Lee se convirtió en la World Wide
Web y sus primeros servidores y navegadores funcionaron en el CERN.
Al año siguiente, la Red se extendió de su laboratorio de física de
partículas a diversos países del mundo. En base a esta nueva concepción,
los programadores desarrollaron cada vez más mejores navegadores, aunque
generalmente limitados a los sistemas informáticos utilizados por los
científicos.
Sin embargo, tras la declaración del CERN del 30 de abril de 1993,
hicieron su aparición en los ordenadores personales, navegadores
informáticos más simples y fáciles de instalar.
En noviembre de aquel año, la estadounidense "National Center for
Supercomputing Applications" lanzó oficialmente el primer navegador que
permitió el acceso del gran público a la Red
¿Qué puedo hacer en Internet?
Lo primero que querrá hacer es explorar el Web. Vaya a algún sitio de
búsqueda y busque algo en lo que esté interesado. Puede ser un tema de
interés general como el windsurfing, un determinado producto o empresa,
o el nombre de una publicación o persona. También es posible que desee
llevar a cabo una investigación u obtener ayuda para un problema casero.
Si hay una coincidencia, puede saltar mediante un hipervínculo
directamente a la información. Si no hay ninguna coincidencia, vuelva a
definir su búsqueda e inténtelo de nuevo. También puede visitar una
determinada dirección URL sobre la que haya leído o que haya oído
mencionar en televisión.
¿Qué es una dirección URL?
URL es la abreviatura de "Uniform Resource Locator". Es un modo de
dirigirse a información en el Web de forma compacta y nada ambigua:
describe exactamente dónde se encuentra la información. Puede indicar
una dirección URL a su vecino o a un amigo en Australia, y ellos podrán
tener acceso a la misma información que usted obtiene con la misma
dirección URL. Es como una dirección postal o un número de teléfono. Hay
direcciones URL para describir recursos de hipermedia (http://), FTP y
Gopher (gopher:// y ftp://), grupos de debate [news://), etc.
¿Qué significa el mensaje "Dirección URL no reconocida"?
La dirección URL puede ser incorrecta o estar incompleta, o bien la
página o información a la que apunta puede haberse trasladado o
eliminado. Si ha escrito la dirección URL, asegúrese de que lo ha hecho
correctamente.
¿Qué es hipertexto e hipermedia?
"Hipertexto" e "hipermedia" son texto o gráficos que tienen vínculos
incrustados. Los vínculos de hipertexto e hipermedia, también llamados
hipervínculos, se activan haciendo clic sobre una palabra subrayada o un
gráfico resaltado en un página de Web. Al hacer clic sobre un
hipervínculo se traslada a otro documento. Estos documentos pueden ser
otras páginas de información, otros sitios Web, películas, fotografías o
sonidos.
¿Qué hace el Web en comparación a Gopher y WAIS?
Gopher fue una parte inicial del Web: organizaba información en menús y
documentos de texto sencillos, pero no tenía las posibilidades reales de
hipertexto o gráficos en línea que lograron la gran expansión de World
Wide Web. WAIS también fue una parte inicial del Web, y lo utilizaban
grandes instituciones para buscar e indexar grandes cantidades de datos.
Los dos siguen usándose bastante y se puede tener acceso a ellos sin
esfuerzo mediante el Explorador de Internet de Microsoft.
¿Pueden contagiarme un virus al mirar en una página de Web?
Si, si puede contagiarse un virus a su PC sólo haciendo clic en alguna
pregunta u opción de ese tipo, ni aunque tenga gráficos, películas o archivos de sonido
o en 3D. también si transfiere un nuevo programa o aplicación y lo
ejecuta, corre el mismo riesgo que al ejecutar cualquier nuevo programa;
por tanto debe tener en cuenta si confía en el sitio desde el que
transfiere el programa. Nada "automático" en el explorador hará que un
virus entre en su equipo.
¿Cómo puedo ejecutar archivos de sonido recogidos de Internet?
Su PC debe tener el equipo y los programas necesarios para producir
sonidos. Si es así, puede transferir archivos de Internet y guardarlos
en disco para escucharlos o modificarlos más adelante, o bien puede
escucharlos en el explorador del Web.
¿Qué son los grupos de debate o NewsGroup?
Los grupos de debate de Usenet son grupos de discusión electrónicos en
los que se puede compartir información y opiniones con personas de todo
el mundo. Dentro de cada grupo de debate encontrará artículos sobre algo
determinado y debates sobre numerosos temas. Los grupos de debate de
Usenet permiten responder a artículos que haya leído y publicar
("enviar") sus propios artículos para que otros los lean. Estos grupos
están organizados y reunidos por título, utilizando nombres compuestos,
como rec.sport.basketball.college. En este caso, rec indica temas de
ocio, sport especifica un subgrupo de deportes, etc.
Correo electrónico
El correo electrónico es la herramienta que permite el cumplimiento de
una de las funciones más importantes de la red de redes Internet: la
interacción. A través del correo electrónico la empresa establece un
contacto permanente con clientes y proveedores brindando a estos un
servicio que al mismo tiempo agrega valor a la empresa. Por medio
del correo electrónico el cliente puede, por ejemplo, llenar un
formulario presupuestario y enviarlo para que la empresa lo evalúe y lo
reenvíe al cliente sin que este se mueva de su oficina.
¿Cómo localizo
la dirección de correo electrónico de alguien?
¡Pregúntele! O bien cuando le envíen correo, mire la dirección "De:". A
menudo, las direcciones de correo electrónico (E-mail) aparecen en las
páginas de Web.
¿Puedo tener
problemas con el correo electrónico?
Sí. Algunas formas son: acosos, envíos de correo no deseado y masivo,
correo encadenado, fraude y tergiversación, y "engaños" (falsificar un
mensaje para que parezca que procede de otro usuario).
¿Qué es un dominio?
El dominio es la denominación que posee la página dentro de la red.
Existen distintos tipos de dominio según la actividad o tipo de
organización que lo posea. Por ejemplo el dominio con la extensión
.com
es comercial, el que utiliza
.edu
es educacional, el
.net
se refiere a los servicios de Internet. Así una empresa con dominio
propio se podría localizar como www.hispamedia.biz; en cambio a una
compañía sin dominio propio sería necesario buscarla como
www.hispmedia.biz/empresa/.
¿Es importante el dominio propio?
A nivel negocio es muy importante tener un dominio propio ya que es como
tener un nombre propio en Internet. Una empresa que no posee dominio
propio pierde presencia en la red ya que depende de un dominio ajeno; en
cambio la empresa que si lo tiene, permite que su URL posea una mayor memorabilidad y brinda una mejor imagen, ya que de esta manera indica
parte del perfil de la compañía y permite conservar el mismo URL aunque
cambie de servidor.
¿Hispamedia
me ayuda a registrar mi dominio?
Claro. Luego de crear su cuenta con nosotros, usted elige el dominio que
desea registrar y listo.
¿Cómo califico para su oferta de dominio gratis?
Muy fácil si aplica para la oferta solo debes asegurarnos que
permanecerá como nuestro cliente
durante el mismo período de vigencia del dominio. En otras palabras,
mientras sea nuestro cliente nunca pagará por el dominio. O simplemente
cuando se tiene esta oferta.
¿Qué
es comercio electrónico?
Es la realización de transacciones económicas por medios electrónicos
como el Internet.
¿Como puedo vender por Internet?
Para vender por Internet es necesario instalar en su sitio un carrito de
compras o "shopping cart", en la cual los usuarios van agregando los
artículos y servicios que comprarán, Estos carritos de compras están
conectados a una base de datos de los productos de su empresa.
¿Qué necesito para validar tarjetas de crédito en línea?
Para poder validar tarjetas de crédito en línea en Internet es necesario
obtener una "Merchant Account". Estas cuentas son otorgadas por
empresas como
CyberCash,
VeriSign,
PaymentNet,
Authorize.NET
y otros.
En Latino America este tipo de cuenta es emitida por los bancos locales.
Hispamedia Network les asesora en como obtener su merchant account lo
más rápido posible.
¿Qué significa
ASP?
ASP es la abreviatura de Active Server Pages que es el lenguaje de
programación dinámica para web creado por Microsoft.
Pero, ¿cúal es la
diferencia de ASP.net con el ASP común que conocemos?
Mucha, realmente es mucha. Mientras ASP
se escribía en VBScript, ASP.net puede ser escrito en cualquier lenguaje
soportado por el .net Framework, es decir: VB.net; C# y JScript.net. Si,
como has leído, ya no puedes utilizar VBScript sino que debes utilizar
VB.net que es lo que más se aproxima. Otro cambio radical es que ASP.net
es un lenguaje totalmente orientado a objetos.
¿Que mejoras trae ASP.net? ¿Es realmente mejor que ASP?
Sin duda, es mucho mejor que el ASP tradicional, ASP.net trae diversas
mejoras entre las cuales se destacan:
Rendimiento: la aplicación de compila en
una sola vez al lenguaje nativo, y luego, en cada petición tiene una
compilación Just In Time, es decir se compila desde el código nativo, lo
que permite mucho mejor rendimiento. También permite el almacenamiento
del caché en el servidor
Rapidez en programación: mediante diversos controles, podemos con unas
pocas líneas y en menos de 5 minutos mostrar toda una base de datos y
hacer rutinas complejas. Servicios Web: trae herramientas para compartir
datos e información entre distintos sitios.
Seguridad: tiene diversas herramientas que garantizan la seguridad de
nuestras aplicaciones.
¿Qué diferencias de sintaxis hay con respecto de ASP 3.0?
Partiendo de la base de que el lenguaje
es otro, muchas, al ser programación orientada a objetos y al ser
lenguaje de Visual Basic .net todo es muy diferente. Hay que cambiar el
pensamiento y todos los viejos conceptos que teníamos de ASP 3.0.
ASP.net es más bien parecido a Visual Basic, en la página, todos los
elementos son objetos, activos de servidor (que se generan ahí) y tienen
propiedades y métodos.
Vale aclarar que en ASP.net existen los
formularios activos del servidor ¿qué es esto?, son como los formularios
tradicionales de HTML, pero se le agrega en el TAG FORM el atributo
runat=server, y dentro del formulario se agregan los controles activos
de servidor. Cuando ocurre un evento, la página se auto envía a si misma
y se procesa el controlador para ese evento.
¿Qué significa PERL?
Es uno de los primeros y más populares lenguaje de programación del
mercado, además de ser muy potente y versátil.
¿Qué es un URL?
URL es la abreviatura de Universal Resourse Locator que significa
localizador de recurso universal. El URL es la dirección de la página en
Internet y el que permite localizarla desde cualquier punto del mundo.
¿Qué es un link o enlace?
Un link es un enlace que conduce al usuario a otra página que puede ser,
o no, del mismo sitio.
¿Qué es el sitio o site?
Es el conjunto de páginas que integran un sitio en la red. Un sitio
puede contener sólo una página.
¿Qué significa hosting u hospedaje?
El proceso de creación de páginas web consta de varias etapas básicas:
el Dominio, el diseño y la publicación(hosting),
registro en buscadores; el hosting se refiere a ésta etapa
en donde se encuentra albergada la información que hace al site,
se controla la cantidad de cuentas de correo, sistema operativo,
velocidad de tranferencia entre otras cosas.
¿Es necesaria una computadora para tener una página en Internet?
No necesariamente ya que la página se encuentra albergada en un servidor
que está conectado las 24 horas del día.
¿Es necesaria una conexión a la red Internet para tener una
página web?
Aunque no sea condición para tener una página en Internet, tener una
computadora con conexión a la red es de mucha importancia ya que permite
el cumplimiento de una de las funciones más importantes de Internet, que
es la interacción.
¿Qué es un buscador?
Los buscadores utilizan ciertos programas llamados también 'robots' o
'arañas'; estos softwares exploran la red y van de página en página
hasta haber visitado hasta el último espacio web de la red.
Cuando un agente de estos programas visita una página web graba el
texto, tanto de la página principal, como de todas las otras que le
siguen. Luego visitará todos los links a los que lleven las páginas;
siguiendo los links, estos buscadores son capaces de encontrar las
páginas aunque el URL no esté publicado en ellos. Así, publicando un URL
en estos buscadores se aligera el proceso: el agente, en lugar de
esperar a que se le notifique la entrada de la página web o encontrarla
por casualidad, irá directamente a ella debido a que ya sabe que está
allí. Existen varios buscadores ejemplos GOOGLE,
YAHOO. ALTAVISTA, MSN, ALLTHEWEB etc
¿Qué es un servidor?
Básicamente, un servidor es una computadora en muchos
casos remota, conectada a la red las 24 horas del día que alberga
la información que contienen las páginas alojadas allí.
¿Que es un CRM?
(del acrónimo inglés "Customer Relationship Management")
Software para la administración de la relación con los clientes.
Sistemas informáticos de apoyo a la gestión de las relaciones con los
clientes, a la venta y al marketing. Con este significado CRM se refiere
al Data warehouse con la información de la gestión de ventas, y de los
clientes de la empresa.
Básicamente, un servidor es una computadora en muchos
casos remota, conectada a la red las 24 horas del día que alberga
la información que contienen las páginas alojadas allí.
Glosario en Ingles:
10BaseT
10 Megabit per second baseband Ethernet specification using two
paris of twisted-pair cabling (Category 3, 4 or 5): one pair for
transmitting data and the other for receiving data. 10BaseT has a
distance limit of approximately 100 meters per segment.
100BaseT
100 Mebabit per second baseband Fast Ehternet specification using
UTP wiring. Like the 10BaseT technology on which it is based, 100BaseT
sends link pulses over the network segment when no traffic is present.
However, these link pulses contain more information than those used in
10BaseT.
A Record
An A record is part of the zone file. It is used to point Internet
traffic to an IP address. For example, you can use an "A record" to
designate abc.yourdomain.com to send traffic to your web site at IP
address 209.15.32.135. You can also designate xyz.yourdomain.com to go
to a separate IP address.
Access [Microsoft®]
MS Access® published by Microsoft is an easy to use and highly
integrated database creation and maintenance software. Capable of online
databases, the software is supported with the NT® hosting platform.
ADSL
(Asymmetric Digital Subscriber Line) -- A method for moving data
over regular phone lines. An ADSL circuit is much faster than a regular
phone connection, and the wires coming into the subscriber's premises
are the same (copper) wires used for regular phone service. An ADSL
circuit must be configured to connect two specific locations, similar to
a leased line.
A commonly discussed configuration of ADSL would allow a subscriber
to receive data (download) at speeds of up to 1.544 Megabits per second,
and to send (upload) data at speeds of 128 kilobits per second. Thus the
'Asymmetric' part of the acronym.
Another commonly discussed configuration would be symmetrical: 384
kilobits per second in both directions. In theory ADSL allows download
speeds of up to 9 megabits per second and upload speeds of up to 640
kilobits per second.
ADSL is often discussed as an alternative to ISDN, allowing
higher speeds in cases where the connection is always to the same place.
Anonymous FTP
Anonymous File Transfer Protocol allows the public to log into an
FTP server with a common login (usually "ftp" or "anonymous" and any
password (usually the person's e-mail address is used as the password).
Anonymous FTP is benefitial for the distribution of large files to the
public, avoiding the need to assign large numbers of login and password
combinations for FTP access.
Applet
A small Java program that can be embedded in an HTML
page. Applets differ from full-fledged Java applications in that they
are not allowed to access certain resources on the local computer, such
as files and serial devices (modems, printers, etc.), and are prohibited
from communicating with most other computers across a network. The
current rule is that an applet can only make an Internet connection to
the computer from which the applet was sent.
Archie
A tool (software) for finding files stored on anonymous FTP
sites. You need to know the exact file name or a substring of it.
ARPANet
(Advanced Research Projects Agency Network) -- The precursor to the
Internet. Landmark packet-switching network established in 1969
by the US Department of Defense as an experiment in wide-area-networking
that would survive a nuclear war.
ASP
ASP - Active Server Pages (ASP). ASP files, which provide Web
developers with an easier, faster, and more powerful way to build Web
applications, are regular HTML pages with embedded scripts. These
scripts can be written in any language and processed by the server when
the file's URL is requested.
ATM
ATM -- Asynchronous Transfer Mode. International sandard for cell
relay in which multiple service types (such as voice, video, or data)
are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow
cell processing to occur in hardware, thereby reducing transit delays.
ATM is designed to take advantage of high-speed transmission media such
as E3, SONET, and T3.
ASCII
(American Standard Code for Information Interchange) -- This is the
de facto world-wide standard for the code numbers used by computers to
represent all the upper and lower-case Latin letters, numbers,
punctuation, etc. There are 128 standard ASCII codes each of which can
be represented by a 7 digit binary number: 0000000 through 1111111, plus
parity.
Backbone
A high-speed line or series of connections that forms a major
pathway within a network. The term is relative, as a backbone in a small
network will likely be much smaller than many non-backbone lines
in a large network.
Bandwidth
The difference between the highest and lowest frequencies available
for network signals. The term is also used to describe the rated
throughput capacity of a given network medium or protocol. In short,
bandwidth is a loose term used to describe the throughput capacity (measured
in Kilobits or Megabits per second) of a specific circuit.
Baud
Unit of signaling speed equal to the number of discrete signal
elements transmited per second. Baud is synonymous with bits per second
(bps). In common usage the baud rate of a modem is how many
bits it can send or receive per second. Technically, baud is the
number of times per second that the carrier signal shifts value - for
example a 1200 bit-per-second modem actually runs at 300 baud, but it
moves 4 bits per baud (4 x 300 = 1200 bits per second).
BBS (Bulletin Board System)
A computerized meeting and announcement system that allows people to
carry on discussions, upload and download files, and make announcements
without the people being connected to the computer at the same time.
There are many thousands (millions?) of BBS's around the world, most are
very small, running on a single IBM clone PC with 1 or 2 phone lines.
Some are very large and the line between a BBS and a system like
CompuServe gets crossed at some point, but it is not clearly drawn.
Binhex
(BINary HEXadecimal) -- A method for converting non-text files
(non-ASCII) into ASCII. This is needed because Internet e-mail
can only handle ASCII.
Bit
(Binary DigIT) -- A single digit number in base-2, in other words,
either a 1 or a zero. The smallest unit of computerized data.
Bandwidth is usually measured in bits-per-second.
BITNET
(Because It's Time NETwork (or Because It's There NETwork)) -- A
network of educational sites separate from the Internet, but e-mail
is freely exchanged between BITNET and the Internet. Listservs,
the most popular form of e-mail discussion groups, originated on BITNET.
BITNET machines are usually mainframes running the VMS operating system,
and the network is probably the only international network that is
shrinking.
Bps
(Bits-Per-Second) -- A measurement of how fast data is moved from
one place to another. A 28.8 modem can move 28,800 bits per
second.
Browser
Client software that is used to look at various kinds of Internet
resources. Examples include Microsoft's Internet Explorer and Netscape's
Navigator.
BTW
(By The Way) -- A shorthand appended to a comment written in an
online forum.
Byte
A set of Bits that represent a single character. Usually there are 8
Bits in a Byte, sometimes more, depending on how the measurement is
being made.
Certificate Authority
An issuer of Security Certificates used in SSL
connections.
CGI
(Common Gateway Interface) -- A set of rules that describe how a
Web Server communicates with another piece of software on the
same machine, and how the other piece of software (the 'CGI program')
talks to the web server. Any piece of software can be a CGI program if
it handles input and output according to the CGI standard.
Usually a CGI program is a small program that takes data from a web
server and does something with it, like putting the content of a form
into an e-mail message, or turning the data into a database query.
CGI "scripts" are just scripts which use CGI. CGI is often confused
with Perl, which is a programming language, while CGI is an interface to
the server from a particular program. Perl is an application of CGI, as
well as MIVA, Python, PHP3, and other scripting languages.
cgi-bin
The most common name of a directory on a web server in which CGI
programs are stored. The 'bin' part of 'cgi-bin' is a shorthand version
of 'binary', because once upon a time, most programs were referred to as
'binaries'. In real life, most programs found in cgi-bin directories are
text files -- scripts that are executed by binaries located elsewhere on
the server. While most programs using CGI are stored in this directory,
it is not a requirement for using CGI.
Client
A software program that is used to contact and obtain data from a
server software program on another computer, often across a great
distance. Each client program is designed to work with one or more
specific kinds of server programs, and each server requires a specific
kind of client. A web browser and an FTP program are specific kinds of
clients.
Co-Location
Network Operations Centers offer the ability for customers to place
their webservers and other network equipment in thier NOC which are
connected via high speed fiber data lines to the backbone of the
Internet. Administration is done remotely so that a customer far away
can configure and control their network equipment.
Cold Fusion
Cold Fusion is a scripting language for web designers that want wish
to do advanced development and/or database interfacing. Cold Fusion
supports MS Access, dBASE, FoxPro, and Paradox databases.
Contact Record
In the case of many registries, contact information for technical,
billing and administrative purposes are maintained in their database. It
is important to keep your contact records updated to ensure that billing
and renewal can proceed without problems.
Cookie
The most common meaning of 'Cookie' on the Internet refers to a
piece of information sent by a Web Server to a Web Browser
that the Browser software is expected to save and to send back to the
Server whenever the browser makes additional requests from the Server.
Depending on the type of Cookie used, and the Browser's settings, the
Browser may accept or not accept the Cookie, and may save the Cookie for
either a short time or a long time.
Cookies might contain information such as login or registration
information, online 'shopping cart' information, user preferences, etc.
When a Server receives a request from a Browser that includes a
Cookie, the Server is able to use the information stored in the Cookie.
For example, the Server might customize what is sent back to the user,
or keep a log of particular user's requests.
Cookies are usually set to expire after a predetermined amount of
time and are usually saved in memory until the Browser software is
closed down, at which time they may be saved to disk if their 'expire
time' has not been reached.
Cookies do not read your hard drive and send your
life story to the CIA, but they can be used to gather more information
about a user than would be possible without them.
Cyberpunk
Cyberpunk was originally a cultural sub-genre of science fiction
taking place in a not-so-distant, dystopian, over-industrialized
society. The term grew out of the work of William Gibson and Bruce
Sterling and has evolved into a cultural label encompassing many
different kinds of human, machine, and punk attitudes. It includes
clothing and lifestyle choices as well.
Cyberspace
Term originated by author William Gibson in his novel Neuromancer
the word Cyberspace is currently used to describe the whole range of
information resources available through computer networks.
DNS: Domain Naming System
The DNS is a distributed, replicated that allows nameservers to map
easily remembered domain names to an IP number.
Dedicated Server
For those customers that want the advantages of colocation without
the hassles of purchasing their own server. See colocation.
Digerati
The digital version of literati, it is a reference to a vague cloud
of people seen to be knowledgeable, hip, or otherwise in-the-know in
regards to the digital revolution.
Domain Name
The unique name that identifies an Internet site. Domain Names
always have 2 or more parts, separated by dots. The part on the left is
the most specific, and the part on the right is the most general. A
given machine may have more than one Domain Name but a given Domain Name
points to only one machine. For example, the domain names:
communitech.net, ftp.communitech.net, whatever.communitech.net can all
refer to the same machine, but each domain name can refer to no more
than one machine.
Usually, all of the machines on a given Network will have the same
thing as the right-hand portion of their Domain Names in the examples
above. It is also possible for a Domain Name to exist but not be
connected to an actual machine. This is often done so that a group or
business can have an Internet e-mail address without having to establish
a real Internet site. In these cases, some real Internet machine must
handle the mail on behalf of the listed Domain Name.
E-Commerce
Electronic Commerce. Refers to the general exchange of goods and
services via the Internet.
E-mail
(Electronic Mail) -- Messages, usually text, sent from one person to
another via computer. E-mail can also be sent automatically to a large
number of addresses (Mailing List).
Ethernet
A very common method of networking computers in a LAN.
Ethernet will handle about 10,000,000 bits-per-second and can be used
with almost any kind of computer.
FAQ
(Frequently Asked Questions) -- FAQs are documents that list and
answer the most common questions on a particular subject. There are
hundreds of FAQs on subjects as diverse as Pet Grooming and
Cryptography. FAQs are usually written by people who have tired of
answering the same question over and over.
FDDI
(Fiber Distributed Data Interface) -- A standard for transmitting
data on optical fiber cables at a rate of around 100,000,000
bits-per-second (10 times as fast as Ethernet, about twice as
fast as T-3).
Finger
An Internet software tool for locating people on other Internet
sites. Finger is also sometimes used to give access to non-personal
information, but the most common use is to see if a person has an
account at a particular Internet site. Many sites do not allow incoming
Finger requests, but many do.
Fire Wall
A combination of hardware and software that separates a LAN
into two or more parts for security purposes.
Flame
Originally, flame meant to carry forth in a passionate manner in the
spirit of honorable debate. Flames most often involved the use of
flowery language and flaming well was an art form. More recently flame
has come to refer to any kind of derogatory comment no matter how
witless or crude.
Flame War When an online discussion degenerates into a series
of personal attacks against the debaters, rather than discussion of
their positions. A heated exchange.
FrontPage Microsoft® FrontPage® is a site creation and
management software tool. One of the most popular website creation
software packages the software, both FrontPage® 98 and FrontPage ®2000
is widely supported by the hosting community.
FTP
(File Transfer Protocol) -- A very common method of moving files
between two Internet sites. FTP is a special way to login to
another Internet site for the purposes of retrieving and/or sending
files. There are many Internet sites that have established publicly
accessible repositories of material that can be obtained using FTP, by
logging in using the account name anonymous, thus these sites are called
anonymous ftp servers.
Gateway
The technical meaning is a hardware or software set-up that
translates between two dissimilar protocols, for example Prodigy has a
gateway that translates between its internal, proprietary e-mail format
and Internet e-mail format. Another, sloppier meaning of gateway is to
describe any mechanism for providing access to another system, e.g. AOL
might be called a gateway to the Internet.
Gigabyte
1024 Megabytes
Gopher
A widely successful method of making menus of material available
over the Internet. Gopher is a Client and Server style
program, which requires that the user have a Gopher Client
program. Although Gopher spread rapidly across the globe in only a
couple of years, it has been largely supplanted by Hypertext, also known
as WWW (World Wide Web). There are still thousands of Gopher
Servers on the Internet and we can expect they will remain for a
while.
hit
As used in reference to the World Wide Web, 'hit' means a single
request from a web browser for a single item from a web server;
thus in order for a web browser to display a page that contains 3
graphics, 4 'hits' would occur at the server: 1 for the HTML
page, and one for each of the 3 graphics.
'hits' are often used as a very rough measure of load on a server,
e.g. 'Our server has been getting 300,000 hits per month.' Because each
'hit' can represent anything from a request for a tiny document (or even
a request for a missing document) all the way to a request that requires
some significant extra processing (such as a complex search request),
the actual load on a machine from 1 hit is almost impossible to define.
Home Page (or Homepage)
Several meanings. Originally, the web page that your
browser is set to use when it starts up. The more common meaning
refers to the main web page for a business, organization, person or
simply the main page out of a collection of web pages, e.g. 'Check out
so-and-so's new Home Page.'
Another sloppier use of the term refers to practically any web page
as a 'homepage,' e.g. 'That web site has 65 homepages and none of them
are interesting.'
Host
Any computer on a network that is a repository for services
available to other computers on the network. It is quite common
to have one host machine provide several services, such as WWW
and USENET.
Hosting
This term can be used to refer to the housing of a web site, email
or a domain. See Email hosting and Web Site hosting for more details.
HTML
(HyperText Markup Language) -- The coding language used to create
Hypertext documents for use on the World Wide Web. HTML looks
a lot like old-fashioned typesetting code, where you surround a block of
text with codes that indicate how it should appear, additionally, in
HTML you can specify that a block of text, or a word, is linked to
another file on the Internet. HTML files are meant to be viewed using a
World Wide Web Client Program, such as Netscape or
Mosaic.
HTTP
(HyperText Transport Protocol) -- The protocol for moving
hypertext files across the Internet. Requires a HTTP
client program on one end, and an HTTP server program on the
other end. HTTP is the most important protocol used in the World Wide
Web (WWW).
Hypertext
Generally, any text that contains links to other documents - words
or phrases in the document that can be chosen by a reader and which
cause another document to be retrieved and displayed.
IMHO
(In My Humble Opinion) -- A shorthand appended to a comment written
in an online forum, IMHO indicates that the writer is aware that they
are expressing a debatable view, probably on a subject already under
discussion. One of may such shorthands in common use online, especially
in discussion forums.
Index Server
Index Server indexes the contents and properties of documents on an
Internet or intranet Web site served by IIS 4.0. Index Server enables
Web clients with any browser to search a Web site by filling in the
fields of an HTML query form.

Internet
(Upper case I) The vast collection of inter-connected
networks that all use the TCP/IP protocols and that evolved from the
ARPANET of the late 60's and early 70's. The Internet now (July
1995) connects roughly 60,000 independent networks into a vast global
internet.
internet
(Lower case i) Any time you connect 2 or more networks
together, you have an internet - as in inter-national or inter-state.
InterNIC
InterNIC (now known as Network Solutions) currently holds an
exclusive contract with the U.S. government to assign domain names for
.COM, .NET and .ORG. The contract is scheduled to expire September 30,
1998. Network Solutions is the company that runs the InterNIC registry.
Intranet
A private network inside a company or organization that uses
the same kinds of software that you would find on the public Internet,
but that is only for internal use.
As the Internet has become more popular many of the tools used on the
Internet are being used in private networks, for example, many companies
have web servers that are available only to employees.
Note that an Intranet may not actually be an
internet
-- it may simply be a
network.
IP Number
(Internet Protocol Number) -- Sometimes called a dotted quad. A
unique number consisting of 4 parts separated by dots, e.g.165.113.245.2
Every machine that is on the Internet has a unique IP number - if a
machine does not have an IP number, it is not really on the Internet.
Most machines also have one or more Domain Names that are easier
for people to remember.
IRC
(Internet Relay Chat) -- Basically a huge multi-user live chat
facility. There are a number of major IRC servers around the
world which are linked to each other. Anyone can create a channel and
anything that anyone types in a given channel is seen by all others in
the channel. Private channels can (and are) created for multi-person
conference calls.
ISDN
(Integrated Services Digital Network) -- Basically a way to move
more data over existing regular phone lines. ISDN is rapidly becoming
available to much of the USA and in most markets it is priced very
comparably to standard analog phone circuits. It can provide speeds of
roughly 128,000 bits-per-second over regular phone lines. In practice,
most people will be limited to 56,000 or 64,000 bits-per-second.
ISP
(Internet Service Provider) -- An institution that provides access
to the Internet in some form, usually for money.
Java
Java is a network-oriented programming language invented by Sun
Microsystems that is specifically designed for writing programs that can
be safely downloaded to your computer through the Internet and
immediately run without fear of viruses or other harm to your computer
or files. Using small Java programs (called "Applets"), Web pages
can include functions such as animations, calculators, and other fancy
tricks.
We can expect to see a huge variety of features added to the Web
using Java, since you can write a Java program to do almost anything a
regular computer program can do, and then include that Java program in a
Web page.
JDK
(Java Development Kit) -- A software development package from Sun
Microsystems that implements the basic set of tools needed to write,
test and debug Java applications and applets
Kilobyte
A thousand bytes. Actually, usually 1024 (210)
bytes.
LAN
(Local Area Network) -- A computer network limited to the immediate
area, usually the same building or floor of a building.
Leased-line
Refers to a phone line that is rented for exclusive 24-hour, 7
-days-a-week use from your location to another location. The highest
speed data connections require a leased line.
Listserv
The most common kind of maillist, Listservs originated on
BITNET but they are now common on the Internet.
Local Registry Fees
Most TLDs require initial registration fees as well as annual or
bi-annual renewal fees. Prices vary from cost-free to thousands of
dollars per domain depending on the TLD chosen. For example, .COM
domains cost which covers the first two years. Re newal fees for .COM
are annually after the first two years expire.
Login
Noun or a verb. Noun: The account name used to gain access to a
computer system. Not a secret (contrast with Password). Verb: The
act of entering into a computer system, e.g. Login to the WELL and
then go to the GBN conference.
Maillist
(or Mailing List) A (usually automated) system that allows
people to send e-mail to one address, whereupon their message is
copied and sent to all of the other subscribers to the maillist. In this
way, people who have many different kinds of e-mail access can
participate in discussions together.
Megabyte
A million bytes. A thousand kilobytes.
MIDI
Musical Instrument Digital Interface -- A network and accompanying
protocol developed in the 1970's for tranmitting various information
between musical and other devices including keyboards, samplers, lights,
controllers, etc.
MIME
(Multipurpose Internet Mail Extensions) -- The standard for
attaching non-text files to standard Internet mail messages. Non-text
files include graphics, spreadsheets, formatted word-processor
documents, sound files, etc.
An email program is said to be MIME Compliant if it can both send and
receive files using the MIME standard.
When non-text files are sent using the MIME standard they are
converted (encoded) into text - although the resulting text is not
really readable.
Generally speaking the MIME standard is a way of specifying both the
type of file being sent (e.g. a QuicktimeÅ video file), and the method
that should be used to turn it back into its original form.
Besides email software, the MIME standard is also universally used by
Web Servers to identify the files they are sending to Web
Clients, in this way new file formats can be accommodated simply by
updating the Browsers' list of pairs of MIME-Types and appropriate
software for handling each type.
Mirror
Generally speaking, 'to mirror' is to maintain an exact copy of
something. Probably the most common use of the term on the Internet
refers to 'mirror sites' which are web sites, or FTP sites
that maintain exact copies of material originated at another location,
usually in order to provide more widespread access to the resource.
Another common use of the term 'mirror' refers to an arrangement
where information is written to more than one hard disk simultaneously,
so that if one disk fails, the computer keeps on working without losing
anything.
Modem
(MOdulator, DEModulator) -- A device that you connect to your
computer and to a phone line, that allows the computer to talk to other
computers through the phone system. Basically, modems do for computers
what a telephone does for humans.
Modify (Domain Name)
The database that the TLD registries maintain need to be accurate in
order for name resolution, billing, renewal notices and public records
to be processed correctly. Typically modifications are required when
nameservers need to change or the contacts change email or postal
address or phone number. The procedures for modifying records will
depend on the registry.
MOO
(Mud, Object Oriented) -- One of several kinds of multi-user
role-playing environments, so far only text-based.
Mosaic
The first WWW browser that was available for the Macintosh,
Windows, and UNIX all with the same interface. Mosaic really started the
popularity of the Web. The source-code to Mosaic has been licensed by
several companies and there are several other pieces of software as good
or better than Mosaic, most notably, Netscape.
MUD
(Multi-User Dungeon or Dimension) -- A (usually text-based)
multi-user simulation environment. Some are purely for fun and flirting,
others are used for serious software development, or education purposes
and all that lies in between. A significant feature of most MUDs is that
users can create things that stay after they leave and which other users
can interact with in their absence, thus allowing a world to be built
gradually and collectively.
MUSE
(Multi-User Simulated Environment) -- One kind of MUD - usually with
little or no violence.
MX Record: Mail Exchange
Mail Exchange record is part of the zone file and is used to
designate which mail server machine should process email for a specific
domain.
NT
Windows NT® is Microsoft's® 32-bit operating system developed from
what was originally intended to be OS/2 3.0 before Microsoft ®and IBM
ceased joint development of OS/2. Used by web hosting companies in the
network environment to offer customers support for Microsoft base
products such as MS Access®, MS SQL® 7.0, and FrontPage® 2000.
Name Servers
A computer that performs the mapping of easily remembered domain
names to IP addresses. Sometimes referred to as a host server.
Netiquette
The etiquette on the Internet. See Also:
Internet
Netizen
Derived from the term citizen, referring to a citizen of the
Internet, or someone who uses networked resources. The term connotes
civic responsibility and participation. See Also:
Internet
Netscape®
A WWW Browser and the name of a company. The Netscape (tm)
browser was originally based on the Mosaic program developed at
the National Center for Supercomputing Applications (NCSA).
Netscape has grown in features rapidly and is widely recognized as
the best and most popular web browser. Netscape corporation also
produces web server software.
Netscape provided major improvements in speed and interface over
other browsers, and has also engendered debate by creating new elements
for the HTML language used by Web pages -- but the Netscape
extensions to HTML are not universally supported.
The main author of Netscape, Mark Andreessen, was hired away from the
NCSA by Jim Clark, and they founded a company called Mosaic
Communications and soon changed the name to Netscape Communications
Corporation.
Network
Any time you connect 2 or more computers together so that they can
share resources, you have a computer network. Connect 2 or more networks
together and you have an internet.
Newsgroup
The name for discussion groups on USENET. See Also:
USENET
NIC
(Networked Information Center) -- Generally, any office that handles
information for a network. The most famous of these on the Internet is
Network Solutions, which is where new domain names are registered.
Another definition: NIC also refers to Network Interface Card which
plugs into a computer and adapts the network interface to the
appropriate standard. ISA, PCI, and PCMCIA cards are all examples of
NICs.
NNTP
(Network News Transport Protocol) -- The protocol used by client
and server software to carry USENET postings back and
forth over a TCP/IP network. If you are using any of the
more common software such as Netscape, Nuntius, Internet
Explorer, etc. to participate in newsgroups then you are
benefiting from an NNTP connection.
Node
Any single computer connected to a network.
OC-3
Refers to a circuit that transmits 155,000,000 bits per second. This
is the size of the largest Internet backbone providers networks.
Packet Switching
The method used to move data around on the Internet. In
packet switching, all the data coming out of a machine is broken up into
chunks, each chunk has the address of where it came from and where it is
going. This enables chunks of data from many different sources to
co-mingle on the same lines, and be sorted and directed to different
routes by special machines along the way. This way many people can use
the same lines at the same time.
Parking (Domain Name)
Registries require the use of name servers or hosts for every domain
registered. Parking is the process by which someone selects a domain
name, and "parks" it by registering the domain name under someone's name
servers. Parking can be done by anyone, to anyone else who has active
name servers. However, parking a domain name alone will result in no
service (webhosting, e-mail) for that particular domain name.
Password
A code used to gain access to a locked system. Good passwords
contain letters and non-letters and are not simple combinations such as
virtue7. A good password might be: Hot-6
Plug-in
A (usually small) piece of software that adds features to a larger
piece of software. Common examples are plug-ins for the Netscape®
browser and web server. Adobe Photoshop® also uses plug-ins.
The idea behind plug-in's is that a small piece of software is loaded
into memory by the larger program, adding a new feature, and that users
need only install the few plug-ins that they need, out of a much larger
pool of possibilities. Plug-ins are usually developed by a third party.
POP
(Point of Presence, also Post Office Protocol) -- Two commonly used
meanings: Point of Presence and Post Office Protocol. A Point of
Presence usually means a city or location where a network can be
connected to, often with dial up phone lines. So if an Internet company
says they will soon have a POP in Belgrade, it means that they will soon
have a local phone number in Belgrade and/or a place where leased lines
can connect to their network. A second meaning, Post Office Protocol
refers to the way e-mail software such as Eudora gets mail from a mail
server. When you obtain a SLIP, PPP, or shell account you almost always
get a POP account with it, and it is this POP account that you tell your
e-mail software to use to get your mail.
Port
3 meanings. First and most generally, a place where information goes
into or out of a computer, or both. E.g. the serial port on a personal
computer is where a modem would be connected.
On the Internet port often refers to a number that is part of a
URL, appearing after a colon (:) right after the domain name.
Every service on an Internet server listens on a particular port
number on that server. Most services have standard port numbers, e.g.
Web servers normally listen on port 80. Services can also listen on
non-standard ports, in which case the port number must be specified in a
URL when accessing the server, so you might see a URL of the form:
gopher://peg.cwis.uci.edu:7000/
shows a gopher server running on a non-standard port (the standard
gopher port is 70). Finally, port also refers to translating a piece of
software to bring it from one type of computer system to another, e.g.
to translate a Windows program so that is will run on a Macintosh.
Posting
A single message entered into a network communications system. E.g.
A single message posted to a newsgroup or message board. See
Also:
Newsgroup
PPP
(Point to Point Protocol) -- Most well known as a protocol that
allows a computer to use a regular telephone line and a modem to
make TCP/IP connections and thus be really and truly on the
Internet.
Propagation
The process whereby the nameservers throughout the world have
updated their records for a specific domain. For example, if you move
your domain from one host to another, it will take around 24 hours or so
for the new address to broadcast everywhere. During that 24 hour period,
the traffic is decreasing at the old location and increasing at the new
location.
PSTN
(Public Switched Telephone Network) -- The regular old-fashioned
telephone system.
Real Audio / Real Video
Real Audio/Real Video enables users of personal computers and other
consumer electronic devices to send and receive audio, video and other
multimedia services using the Web.
enable users of personal computers and other consumer electronic
devices to send and receive audio, video and other multimedia services
using the Web.
Register (Domain Name)
Since every domain is unique, registries have been set up to assign
domains to individuals and organziations. When a domain is registered
with the appropriate registry, that domain is assigned and becomes no
longer available for anyone else to use. Typically, there are
registration and renewal fees (local registry fees) associated with the
right to use a domain. However, there are some TLDs that are provided at
no charge.
Registrant (Domain Name)
The entity, organization or individual that will be using the domain
name.
Registrar (Domain Name)
Some registries don't provide the ability for end users to register
domains with them directly. They might require end users to purchase the
domain through an internet provider that is acting as the registrar.
Registry (Domain Name)
An organization responsible for assigning domain names for the TLD
that they manage. Furthermore, it is their responsibility to update the
global DNS tables that all nameservers use to resolve domain names. For
example, InterNIC is the registry for .COM, .NET and .ORG domain names.
Renewal (Domain Name)
Most TLDs need to be renewed at some scheduled yearly interval. This
is an opportunity for both the registrant and the registry to update
their records as well as collect any applicable renewal fees.
Resolution (domain Name)
The conversion of an internet address or domain name into the
corresponding physical location.
RFC
(Request For Comments) -- The name of the result and the process for
creating a standard on the Internet. New standards are proposed
and published on line, as a Request For Comments. The Internet
Engineering Task Force is a consensus-building body that facilitates
discussion, and eventually a new standard is established, but the
reference number/name for the standard retains the acronym RFC, e.g. the
official standard for e-mail is RFC 822.
Router
A special-purpose computer (or software package) that handles the
connection between 2 or more networks. Routers spend all their
time looking at the destination addresses of the packets passing
through them and deciding which route to send them on.
Security Certificate
A chunk of information (often stored as a text file) that is used by
the SSL protocol to establish a secure connection.
Security Certificates contain information about who it belongs to,
who it was issued by, a unique serial number or other unique
identification, valid dates, and an encrypted 'fingerprint' that can be
used to verify the contents of the certificate.
In order for an SSL connection to be created both sides must have a
valid Security Certificate.
Server
A computer, or a software package, that provides a specific kind of
service to client software running on other computers. The term
can refer to a particular piece of software, such as a WWW
server, or to the machine on which the software is running, e.g.Our mail
server is down today, that's why e-mail isn't getting out. A single
server machine could have several different server software packages
running on it, thus providing many different servers to clients
on the network.
Shockwave
Shockwave, produced by Macromedia, allows you to view new forms of
entertainment on the Web, such as games, music, rich-media chat,
interactive product demos, and e-merchandising applications
SLIP
(Serial Line Internet Protocol) -- A standard for using a regular
telephone line (a serial line) and a modem to connect a computer
as a real Internet site. SLIP is gradually being replaced by
PPP.
SMDS
(Switched Multimegabit Data Service) -- A new standard for very
high-speed data transfer.
SMTP
(Simple Mail Transport Protocol) -- The main protocol used to send
electronic mail on the Internet.
SMTP consists of a set of rules for how a program sending mail and a
program receiving mail should interact.
Almost all Internet email is sent and received by clients and
servers using SMTP, thus if one wanted to set up an email server
on the Internet one would look for email server software that supports
SMTP.
SNMP
(Simple Network Management Protocol) -- A set of standards for
communication with devices connected to a TCP/IP network.
Examples of these devices include routers, hubs, and switches.
A device is said to be 'SNMP compatible' if it can be monitored
and/or controlled using SNMP messages. SNMP messages are known as
'PDU's' - Protocol Data Units.
Devices that are SNMP compatible contain SNMP 'agent' software to
receive, send, and act upon SNMP messages.
Software for managing devices via SNMP are available for every kind
of commonly used computer and are often bundled along with the device
they are designed to manage. Some SNMP software is designed to handle a
wide variety of devices.
Spam (or Spamming)
An inappropriate attempt to use a mailing list, or USENET
or other networked communications facility as if it was a broadcast
medium (which it is not) by sending the same message to a large number
of people who didn't ask for it. The term probably comes from a famous
Monty Python skit which featured the word spam repeated over and over.
The term may also have come from someone's low opinion of the food
product with the same name, which is generally perceived as a generic
content-free waste of resources. (Spam is a registered trademark of
Hormel Corporation, for its processed meat product.)
E.g. Mary spammed 50 USENET groups by posting the same message to
each.
SQL
(Structured Query Language) -- A specialized programming language
for sending queries to databases. Most industrial-strength and many
smaller database applications can be addressed using SQL. Each specific
application will have its own version of SQL implementing features
unique to that application, but all SQL-capable databases support a
common subset of SQL.
SSL
(Secure Sockets Layer) -- A protocol designed by Netscape
Communications to enable encrypted, authenticated communications across
the Internet.
SSL used mostly (but not exclusively) in communications between web
browsers and web servers. URL's that begin with
'https' indicate that an SSL connection will be used.
SSL provides 3 important things: Privacy, Authentication, and Message
Integrity.
In an SSL connection each side of the connection must have a
Security Certificate, which each side's software sends to the other.
Each side then encrypts what it sends using information from both its
own and the other side's Certificate, ensuring that only the intended
recipient can de-crypt it, and that the other side can be sure the data
came from the place it claims to have come from, and that the message
has not been tampered with.
Sysop
(System Operator) -- Anyone responsible for the physical operations
of a computer system or network resource. A System Administrator decides
how often backups and maintenance should be performed and the System
Operator performs those tasks.
T-1
A leased-line connection capable of carrying data at
1,544,000 bits-per-second. At maximum theoretical capacity, a T-1
line could move a megabyte in less than 10 seconds. That is still
not fast enough for full-screen, full-motion video, for which you need
at least 10,000,000 bits-per-second. T-1 is the fastest speed commonly
used to connect networks to the Internet.
T-3
A leased-line connection capable of carrying data at
44,736,000 bits-per-second. This is more than enough to do full-screen,
full-motion video.
TCP/IP
(Transmission Control Protocol/Internet Protocol) -- This is the
suite of protocols that defines the Internet. Originally designed
for the UNIX operating system, TCP/IP software is now available
for every major kind of computer operating system. To be truly on the
Internet, your computer must have TCP/IP software.
Telnet
The command and program used to login from one Internet
site to another. The telnet command/program gets you to the login:
prompt of another host.
Terabyte
1024 gigabytes.
Terminal
A device that allows you to send commands to a computer somewhere
else. At a minimum, this usually means a keyboard and a display screen
and some simple circuitry. Usually you will use terminal software in a
personal computer - the software pretends to be (emulates) a physical
terminal and allows you to type commands to a computer somewhere else.
Terminal Server
A special purpose computer that has places to plug in many modems
on one side, and a connection to a LAN or host machine on
the other side. Thus the terminal server does the work of answering the
calls and passes the connections on to the appropriate node. Most
terminal servers can provide PPP or SLIP services if
connected to the Internet.
Top Level Domain: (TLD)
A Top Level Domain (TLD) is the uppermost in the hierarchy of domain
names. For example, communitech.net is our domain name. The "net" is
considered the TLD and the "communitech.net" is considered the second
level domain. Together they form a domain name which is unique. There
are two types of TLDs. The most common type is the Generic or Global
TLDs which include .COM, .NET, .ORG, .MIL, .INT and .EDU. There is a
possibility that new gTLDs will be introduced in the near future.
National or ccTLDs are two letter country code domains that are managed
by a registry designated and controlled by each specific country. Each
registry might have differing prices, residency requirements and
structure.
Trademark
As it relates to domain names... a word, phrase or slogan used to
identify and distinguish the source of the goods or services. Trademark
law may be different worldwide. If someone registers a domain name such
as microsoft.to then Microsoft would need to go to the courts in Tonga
to fight to get the name back. Expensive international litigation is one
reason why it is important to protect your trademarks before someone
else registers the names.
Transfer (Domain Name)
On occasion, domains are sold to another organization or sometimes
the name of a company might change. Most registries require a letter of
permission from the old owner to hand over control to the new owner. The
procedures for Transfer of ownership will depend on the registry.
TTFN
(Ta Ta For Now) -- A shorthand appended to a comment written in an
online forum. See Also:
IMHO ,
BTW
UNIX
A computer operating system (the basic software running on a
computer, underneath things like word processors and spreadsheets). UNIX
is designed to be used by many people at the same time (it is
multi-user) and has TCP/IP built-in. It is the most common
operating system for servers on the Internet.
URL
(Uniform Resource Locator) -- The standard way to give the address
of any resource on the Internet that is part of the World Wide Web
(WWW). A URL looks like this: http://www.communitech.net/glossary/ or
telnet://anywhere.you.want or news:new.newusers.questions etc.
The most common way to use a URL is to enter into a WWW browser
program, such as Netscape, or Lynx.
USENET
A world-wide system of discussion groups, with comments passed among
hundreds of thousands of machines. Not all USENET machines are on the
Internet, maybe half. USENET is completely decentralized, with over
10,000 discussion areas, called newsgroups. See Also:
Newsgroup
UUENCODE
(Unix to Unix Encoding) -- A method for converting files from
Binary to ASCII (text) so that they can be sent across the
Internet via e-mail.
Veronica
(Very Easy Rodent Oriented Net-wide Index to Computerized Archives)
-- Developed at the University of Nevada, Veronica is a constantly
updated database of the names of almost every menu item on thousands of
gopher servers. The Veronica database can be searched from most
major gopher menus. See Also:
Gopher

portable, lightweight interpreter for use in World Wide Web browsers and
other applications that use Microsoft® ActiveX® Controls, Automation
servers, and Java applets Souce:
http://msdn.microsoft.com/scripting/default.htm
WAIS
(Wide Area Information Servers) -- A commercial software package
that allows the indexing of huge quantities of information, and then
making those indices searchable across networks such as the
Internet. A prominent feature of WAIS is that the search results are
ranked (scored) according to how relevant the hits are, and that
subsequent searches can find more stuff like that last batch and thus
refine the search process.
WAN
(Wide Area Network) -- Any internet or network that
covers an area larger than a single building or campus.
Web
See: WWW
Whois
Most registries maintain a database of domain names and their
associated contact information. Users can query these databases through
a program called Whois.
WWW
(World Wide Web) -- Two meanings - First, loosely used: the whole
constellation of resources that can be accessed using Gopher, FTP,
HTTP, telnet, USENET, WAIS and some other tools. Second, the
universe of hypertext servers (HTTP servers) which are the
servers that allow text, graphics, sound files, etc. to be mixed
together.
Zone file
The group of files that reside on the domain host or nameserver. The
zone file designates a domain, its subdomains and mail server.
