Glossary
We have compiled this glossary to provide some down-to-earth explanations
for some of the unusual words, acronyms and abbreviations used in todays technological jungle.
- Anti-virus
- Program used to stop or prevent your computer
being infected by a computer virus. A computer virus essentially acts like
a biological virus and most usually gets into a computer system through unsolicited
email.
- ASP
- Active Server Pages. One of the many versions
of delivering dynamic content to the internet user.
- B2B
- Business to business.
- B2C
- Business to consumer.
- Backup
- To make a duplicate copy of data. This is done
to protect against data corruption or theft.

computer to another. This also relates to the amount of data that can be sent
between different components in a computer (such as a hard drive or memory).
- BCC
- Blank carbon copy. This is a field specified
in the head of an email that allows you to email the same message to several
people without each recipient knowing about the other.
- Bit
- A bit is the smallest unit of information on
a computer. This is rarely referred to as the more common unit is the byte,
which is a group of 8 bits.
- Browser
- This is the piece of software used to view webpages
on the internet. The most common browsers are Internet Explorer and Netscape.
Most browsers can show images, text and animations but some, mainly used to
give internet access to the blind, only show text content allowing them to
be read out audibly by the computer.
- Byte
- A byte is 8 bits and is the smallest unit of
information commonly referred to in computing.
- CC
- Carbon Copy. This is a field in the head of an
email that allows the sender to include other email addresses as recipients
of the same email.

- Almost every computer in use today has a CD-ROM
drive. The CD-ROM is a form of high-density optical storage that is more commonly
used for audio Compact Discs, but which is also used for data storage and
software distribution. Previously only available as read-only, recent technological
advancements now allow the home user to use a CD-RW (Compact Disc Reader/Writer)
to write data onto blank CD-ROM.

dries are the exception).
- E-Commerce
- Electronic Commerce, allowing customers to purchase
items and conduct financial transactions over the Internet safely and securely.
- E-Mail
- Electronic Mail. E-mail allows people to send
messages from one computer to another via the internet. Email can be plain
text or HTML with embedded images, and an email can have other files "attached"

to be software (such as Norton Personal Firewall or McAfee).
- Flash
- Flash is the industry standard web animation
program produced by Macromedia. Flash allows much increased interactivity,
better audio management, video embedding and much, much more. Over 98% of
internet browsers have at least the Flash 5 plug-in making it better supported
than any other non-standard (ie non-W3C compliant) internet technology.
- FTP
- FTP (File Transfer Protocol) is an internet protocol
designed to allow internet users to transfer files between computers. To transfer
files via FTP the user usually needs an FTP program such as CuteFTP or WS-FTP.
The latest versions of Internet Explorer and Netscape also allow you to use
FTP but does not allow some of the more advanced features available with specialised
software.
- Gb
- Gb stands for Giga byte. A Giga byte is 1,000,000,000
bytes or 1000 Mb. This is not an entirely accurate evaluation but is a good
approximation.
- Hosting
- Hosting is the act of placing a website on a
server, registering that server as the computer that hosts the specific domain
name. This allows the internet user to access the website and gives the website
owner access to their domain email.
- HSP

that operates and maintains a group of computers used for hosting websites
(usually known as a Server Farm or Data Centre).
- HTML
- Hypertext Markup Language. The basic programming
language of the internet. HTML allows text formatting and the placing of images
and other objects on webpages. It is not possible to construct a webpage without
using HTML.
- HTTP
- Hypertext Transfer Protocol. Like FTP, HTTP allows
the transfer of webpages and files. HTTP was designed to allow the delivery
of small files (such as webpages) but can be used to transfer other larger
files (but not as efficiently as FTP). The main difference is that HTTP works
through a webpage only, whereas FTP relies on a direct connection between
two computers.
- IP
- IP (Internet Protocol) specifies the format of
internet information packets called datagrams and the internet address of
the computer (usually in the format 217.168.xxx.xxx). On most comuters IP
is usually combined with TCP (Transmission Control Protocol) which which establishes
a virtual connection between a destination and a source.
- Internet
- The internet is a global network of computers
providing an exchange of data, news and opinions. This is not the World Wide
Web, which is just one small part of the internet. The internet allows access
to the World Wide Web but is much more than that.

- JavaScript
- JavaScript is an internet scripting language,
loosely based around Java (although not a true programming language). JavaScript
integrates seamlessly with HTML and allows websites increased interactivity
and the ability to add dynamic content.
- Kb
- Kilobyte = 1,000 bytes.
- Leased Line
- A dedicated telecommunications link between two
points. Leased lines are available with different bandwidth allowances.
- Mb

manipulation tool used for many tasks, from photo retouching to creating posters.
One of the most versatile and powerful programs available to the designer
it is essential for a professional finish.
- PHP
- PHP Hypertext Preprocessor is a server-side embedded
scripting language that allows increased delivery of dynamic content from
