CATP -- (Caffeine Access Transport Protocol)
Common method of moving caffeine across Wide Area Networks such as the Internet
CATP was first used at the Binary Cafe in Cybertown and quickly spread world-wide.
There are reported problems with short-circuits and rust and decaffinated beverages were not supported until version 1.5.3
CDMA -- (Code Division Multiple Access)
A protocol for wireless data and voice communication, CMDA is widely used in cellphone networks, but also in many other data communications systems. CDMA uses a technique called "Spread Spectrum" whereby the data being transmitted is spread across multiple radio frequencies, making more efficent use of available radio spectrum. There are a number of additional protocols built on top of CDMA, such as 1xRTT (also called CMDA2000).

CGI -- (Common Gateway Interface)
A set of rules that describe how a Web Server communicates with another piece of software on the same machine, and how the other piece of software (the ?CGI program?) talks to the web server. Any piece of software can be a CGI program if it handles input and output according to the CGI standard.
cgi-bin

Client
A software program that is used to contact and obtain data from a Server software program on another computer, often across a great distance. EachClient program is designed to work with one or more specific kinds of Server programs, and each Server requires a specific kind of Client. A Web Browser is a specific kind of Client.
co-location
Most often used to refer to having a server that belongs to one person or group physically located on an Internet-connected network that belongs to another person or group. Usually this is done because the server owner wants their machine to be on a high-speed Internet connection and/or they do not want the security risks of having the server on thier own network.
Content Management System
A software package that enables content to be managed on one or more websites. A content management system allows one or more authors to prepare and publish information online, without needing to prepare HTML code.
Cookie
The most common meaning of "Cookie" on the Internet refers to a piece of information sent by a Web Server to a Web Browser that the Browser software is expected to save and to send back to the Server whenever the browser makes additional requests from the Server.
Depending on the type of Cookie used, and the Browsers' settings, the Browser may accept or not accept the Cookie, and may save the Cookie for either a short time or a long time.
Cookies might contain information such as login or registration information, online "shopping cart" information, user preferences, etc.
When a Server receives a request from a Browser that includes a Cookie, the Server is able to use the information stored in the Cookie. For example, the Server might customize what is sent back to the user, or keep a log of particular users' requests.
Cookies are usually set to expire after a predetermined amount of time and are usually saved in memory until the Browser software is closed down, at which time they may be saved to disk if their "expire time" has not been reached.
Cookies do not read your hard drive and send your life story to the CIA, but they can be used to gather more information about a user than would be possible without them.
CSS -- (Cascading Style Sheet)
A standard for specifying the appearance of text and other elements. CSS was developed for use with HTML in Web pages but is also used in other situations, notably in applications built using XPFE. CSS is typically used to provide a single "library" of styles that are used over and over throughout a large number of related documents, as in a web site. A CSS file might specify that all numbered lists are to appear in italics. By changing that single specification the look of a large number of documents can be easily changed.
