CGI

Common Gateway Interface (CGI) describes a server-side program that receives and processes information sent from a web form.

CGI programs are the most common way to exchange and process information between a web page. They can be written in any practically any programming language and are run on web servers.

Function

A function is a named group of statements in a program that performs a task when it is invoked.

Other programming languages make a distinction between a function, which returns a value, and a procedure, which performs some operation but does not return a value. Since JavaScript does not make this distinction, you can create functions that return values elsewhere in your code.

MPEG

MPEG, for Moving Picture Experts Group, refers to a group of audio/video compression standards used to create videos.

To view an MPEG video, you need to download (shareware or commercial) client software that plays it. The MPEG group works within the International Organization for Standardization and periodically improves and updates the compression standards.

Proxy


A proxy server is a machine used to secure and speed up traffic on a network. The server directs traffic between workstations and web servers, filters requests made to the Web, or blocks them altogether. The server can be set with specific rules, such as blocking prohibited sites or closing certain ports. Proxy servers can also streamline network performance:For example when a user requests a web page, the server will cache the page and have it ready if another user requests it.

Tag (Design)

The HTML tag is a formatting command that comes in two parts:a beginning and a closing tag. Bracketing text between a beginning bold tag and an ending bold tag (like so:
<bold>text</bold>
) will, indeed, make it bold. The difference between a beginning and an ending tag is the “/” on the latter. Over time, some ending tags have become implied, most notably the
</>
tag, but don’t be lazy. Tags are used to describe a document’s structure as well as its visual formatting. Because browsers differ in how they display web pages, you should always include structural tags like
<head>
and
<body>
