Glossary
Often people come across words and phrases they don’t understand
– here is a helpful guide to explain some of the most common
terminology.
Accessibility
In the context of a Web site, accessibility refers to the degree
that a Web site can be accessed by people with disabilities.
Apache
The most popular Web server software in use today. An August
2006 survey found that over 62% of Web sites use Apache. Our
hosting is on Apache servers
Bandwidth
Bandwidth is a measure of how fast data that can be transferred
between two computers. Popular units include Kilobits per second
(Kbps) or MegaBits per second (Mbps).
Cache
Copies of previously accessed Web pages and associated files are
stored (in a cache) on a user's computer or on computers operated
by an ISP. On subsequent visits to these Web pages the files are
retrieved from the cache rather than downloaded from the Web server
again. This reduces the time taken to deliver the Web page to the
user.

Cascading Style Sheets (CSS)
A technology used to control the presentation (and often the
layout) of a Web page. CSS controls colours, font faces, text
sizes, etc. We use this technology.
Client Side
A description of technologies (for example: JavaScript and
Macromedia Flash) that are downloaded and run by the user's Web
browser rather than on the Web server. Client side technologies
often require a Web browser to have a plug-in installed.
Code-editor
A type of authoring tool that allows you to directly edit the
HTML source of a Web page.
Common Gateway Interface (CGI)
A set of rules allowing a user's Web browser to communicate with
a program on the Web server. For example, after submitting a Web
form the data from that form is passed through the CGI to a program
on the server. This program processes the data and then emails the
data from the form to an appropriate recipient. We use this
technology.
Content Management System (CMS)
In the context of a Web site a CMS is a collection of tools

HyperText Transfer Protocol (HTTP)
The Internet is made up of computers communicating with each
other through standard protocols. HyperText is one such protocol
and is the one used to transfer Web pages.
Information Architecture
The design and structure of an information system (in this case
a Web site). Good information architecture ensures that data is
structured so that information can be easily found by the user.
Internet
The Internet is worldwide collection of computers all connected
together to form a huge network. These computers communicate with
each other through a set of common software standards known as
protocols. These protocols allow the sending and receiving of
emails; viewing of Web pages; the transfer of files between one
computer and another; instant messaging, etc.
Internet Explorer
The most common user agent or web browser used to access the
internet. Developed by Microsoft Corporation.
Internet Protocol Address (IP Address)

Internet Service Provider (ISP)
An ISP is an organisation that provides users with connectivity
to the Internet. Usually users pay a fee for the use of an ISP.

Keywords
Words (search terms or phrases) that may be used by viewers

An Apple Macintosh computer.
Mark up
The process by which documents are converted into Web pages by

search engines with valuable information such as keywords.
Modulator-demodulator (Modem)
A device that converts the digital signal from a computer to an
analogue signal that can be transmitted along an ordinary phone
line. This allows computers to connect to the Internet through a
telephone line.
Open Source
An open source program has its source code distributed allowing
programmers to alter and change the original software as much as
they like.
Photoshop

user can interact with through the CGI or more directly through the
Web server itself. Nothing is downloaded to the Web browser so
server side technologies do not require a plug-in.
Title Tag
The contents of the Title tag is generally displayed by the
browser at the top of the browser window. The search engines use
the Title tag to provide a link to the sites which match the query
made by the user. Having keywords in the Title tag of a page can
significantly increase the search engine ranking of the page for
those keywords.
URL and URI (Universal Resource Locator and Uniform Resource
Identifier)

can include producing e-commerce applications or implementing a
site search tool, for example. Occasionally used interchangeably
with 'Web designer'.
