Accessibility
The accessibility of a web page refers to the extent to which users can access the content regardless of the technology they use and any disability they may have. An accessible web page is one that is designed to ensure that this is possible through, for example, providing textual descriptions of graphics used to allow their significance to be described in text-only browsers or via screen-reading software.
Active server pages (ASP)
A framework developed by Microsoft for providing server-side processing capabilities and database functionalities. Now largely superceded by a more-recent version, ASP.NET.
Answering drop-outs

An asynchronous interview will usually involve the interviewer posting to a discussion list or emailing interview questions to respondents to answer at their own convenience. Neither party needs to be online at the same time.
B
Bandwidth
A measure of the amount of data that can be sent through a connection, usually described in Kilobits per second (Kbs).

/>
C
Cache
An area of a computer's memory used to temporarily store files making up web pages (HTML, graphics, CSS, scripts etc) to increase the speed of access to them. When a user moves back to a previously-viewed web page, the browser loads any elements that have not changed from the cache rather than from the server.

Client-side scripting through scripting languages such as JavaScript allows dynamic or interactive features to be added to web pages. Code is added to a web page which is executed in the browser on the client computer. It can be used to, for example, check for the presence of a cookie indicating that a user has visited the site before, and display a different message according to whether the cookie is found. It can also allow users to display or hide content such as help windows or menu bars by clicking on buttons or links, or carry out different actions according to user actions or input.

Hidden form fields
Hidden form fields are form controls that are not displayed on the page (though they are visible in the HTML source for the page). They are useful for storing and passing information from page to page which is not necessary or desirable to display. They can be thought of as text boxes with content that can be set by the developer via HTML or JavaScript rather than being completed by the user.
HTML
HTML (Hyper Text Markup Language) is the technical language that lies behind most web pages. It consists of tags which surround blocks of text to indicate how they should appear in a browser, and which are used to insert elements such as images or tables.
HTML tags
In an HTML document, tags are used to tell the browser how to present the layout and style of text and other elements. Tags can consist of elements, attributes and values. The element indicates what should be displayed in the browser, and the attributes and values indicate how this should be displayed.
e.g. In the following tag, <p align="center">Hello!</p>, <p></p> is the element which tells the browser to display a new paragraph, align is the attribute and center is the value which indicates that it should be displayed with a centered alignment.

J
