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.

Program used to stopor 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.

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.

Firewalls are used to block access to your computer over the internet by malicious hackers, snoopers or intrusive software. The firewall can be software or hardware, but for the home user it is more likely to be software (such as Norton Personal Firewall or McAfee).

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(File Transfer Protocol) is an internet protocol designed to allow internet users to transfer files between computers. To transfer files via FTpthe user usually needs an FTpprogram such as CuteFTpor WS-FTp. The latest versions of Internet Explorer and Netscape also allow you to use FTpbut does not allow some of the more advanced features available with specialised software.

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 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.

Hosting Service Provider. The company or organistaion that operates and maintains a groupof computers used for hosting websites (usually known as a Server Farm or Data Centre).

Hypertext MarkupLanguage. 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.

Hypertext Transfer Protocol. Like FTp, HTTpallows the transfer of webpages and files. HTTpwas 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 HTTpworks through a webpage only, whereas FTprelies on a direct connection between two computers.

Ip(Internet Protocol) specifies the format of internet information packets called datagrams and the internet address of the computer (usually in the format On most comuters Ipis usually combined with TCp(Transmission Control Protocol) which which establishes a virtual connection between a destination and a source.

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 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.

Kilobyte = 1,000 bytes.

Leased Line
A dedicated telecommunications link between two points. Leased lines are available with different bandwidth allowances.

Megabyte = 1,000 Kb = 1,000,000 bytes

Practical Extraction and Report Language, Perl is a programming language especially designed for processing text. Because of its strong text processing abilities, Perl has become one of the most popular languages for writing CGI scripts.

Adobe Photoshopis the industry standard image 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.

PHpHypertext Preprocessor is a server-side embedded scripting language that allows increased delivery of dynamic content from databases. PHpcan perform any task that CGI can, but increased compatability with other technologies (SMTp, POP3 etc) makes it much more powerful.

Post Office Protocol (version 3). The standard protocol usd for the retrieving of email from a mail server.

An agreed-upon format for transmitting data between two devices.

An image where every pixel is explicitly described (also known as a bitmap). Most digital images are raster images.

Uniform Resource Locater. this specifies the global address of documents and other resources on the World Wide Web. For example and are both URL's. The first part specifies the protocol to use, and the second half the Ipaddress or domain name.

Vector is used to describe an image that is made upof curves and lines described by mathematical equations. Generally used for illustration, vector images are resolution independant which means the same image can be used on a letterhead and a billboard poster.

Virtual Private Network, a secure network across the Internet (Virtual) where the data is sent encrypted (private).

World Wide Web Consortium. A organistaion concerned with web standards based at MIT in the USA. Publish a list of definitive standards for internet languages such as HTML, DHTML, XML etc. If the web deisgner/developer follows the sandards of the W3C to the letter, the produced webpage can allegedly be accurately viewed in any browser.
