- 56K Line
- A digital phone-line connection (leased
line) capable of carrying 56,000 bits per second.
At this speed, a megabyte will take
about 3 minutes to transfer. This is 4 times as fast as a 14,400bps modem.
- See Service Provider
- ADN (Advanced Digital Network)
- Usually refers to a 56K bps leased-line.

to represent all the upper and lower-case Latin letters, numbers, punctuation,

by a 7 digit binary number: 0000000 through 1111111. Some character sets
use slightly different versions of this, more suited to their alphabets.
- A file that you inlcude as part of an E-mail

a cable or a modem. Cables may be segmented
For modems, 2400 bits per second is slow, 14,400 is OK,
28,800 what to aim for, anything else is boasting. Full-motion full-screen
video would require roughly 10,000,000 bits-per-second, depending on compression.
- Baud Rate (BPS, bits per second)
- A unit to measure the speed a modem
transmits information, the more bits it can transfer,
the faster the modem. The terms BAUD and BPS are often (incorrectly) interchanged.
Technically, BAUD refers to the number of changes in the electrical signal
and at high rates, the BAUD RATE and BPS are not the same.
- BBS (Bulletin Board System)
- A computerised 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 of BBS's around the world and
many are very small, running on a single PC with 1 or 2 phone lines. Some
are very large - for example a system like Compuserve may be loosely described
as a bulletin board.

completed testing by the manufacturer, but may be on the market already.

use. Binary files can contain graphics, sounds, video, programs or other

The smallest unit of computerized data. Bandwidth
is usually measured in bits per second

Hypertext Links). It can also
be used to do a lot of other things too like FTP and

and email messages
- A set of 8 bits that represent a single character.
- CGI (Common Gateway Interface)
- This is a programming language for servers.
Instead of retrieving a web page for
you, the server runs a program (written in CGI) which may write a new page
on the fly, send you an email or register you on a
- Communications Software
- A program that handles the business of computer to computer communications.
It allows you to set up your modem, dial
out to another computer, write messages and send and receive information.
Many times it is packaged within other software (Windows, Works, Word).
Also called modem software, comm software or term software.What you need
on your computer to use a modem. The good news, much is free or shareware.
- 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
- If two pieces of computer hardware or software are able to communicate
with each other, they are said to be compatible. The Internet
is designed so that all information passed on it can be accessed by any

- Domain Name
- The unique name that identifies an Internet site.
Domain Names always have 2 or more parts, separated by dots. A given machine
may have more than one Domain Name but a given Domain Name points to only
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. Domain Name
can exist as aliases These web pages
are accessed as www.communities.org.uk, even though they resides on a server
which also has the name www.btwebworld.com. This is done so that a group
or business can have an Internet email address without having to establish
a real Internet site.

- A program which converts a domain name into a unique numerical address
or IP Number
- Copying or retrieving a file (text, picture, photo or sound 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
