Wireless Developer Network Glossary
C - C is a structured, procedural programming language that has been widely used both for operating systems and applications and that has had a wide following in the academic community. Many versions of UNIX-based operating systems are written in C.
C++ - C++ is an object-oriented programming language that is viewed by many as the best language for creating large-scale application programs. C++ is a superset of the C language.
Carrier - A company that provides a communications service.
CDMA - Code Division Multiple Access. A spread spectrum air interface technology used in some digital cellular, personal communications services and other wireless networks.
cdma2000 - A third-generation wireless technology proposal submitted to the International Telecommunication Union, which is based on the IS-95, or cdmaOne, standard.
cdmaOne - The IS-95 CDMA standard developed by Qualcomm Inc.; a word coined by the CDMA Development Group.
CDPD - CDPD stands for Cellular Digital Packet Data. It is also referred to as "wireless IP" and is a method of sending and receiving information via mobile devices. CDPD allows information to be sent in "packets" or blocks over the existing analog cellular network. It is best suited for short, periodic bursts of information. CDPD is a wireless transmission method that uses the analog cellular network, also known as Advanced Mobile Phone System (AMPS). CDPD allows information to be transmitted on idle cellular voice channels.
Cell - The area surrounding a cell site. The area in which calls are handled by a particular cell site.
Cell Site - The transmission and reception equipment, including the base station antenna, that connects a cellular phone to the network.
Cellemetry - Uses the cellular network to carry data messaging used for remote services such as utility meter reading, vending machine status and vehicle or trailer tracking.
Certificate - A digital certificate is an electronic "credit card" that establishes your credentials when doing business or other transactions on the Web. It is issued by a certification authority (CA).
Certificate Authority - A CA (certificate authority) is an authority in a network that issues and manages security credentials and public keys for message encryption and decryption.
CGI - The common gateway interface (CGI) is a standard way for a Web server to pass a Web user's request to an application program and to receive data back to forward to the user.
CLEC - Competitive Local Exchange Carrier. A new entrant providing local wireline phone service.
Client/Server - Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request. Although the client/server idea can be used by programs within a single computer, it is a more important idea in a network.
Compiler - A compiler is a special program that processes statements written in a particular programming language and turns them into machine language or "code" that a computer's processor uses.
Control Channel - A logic channel carrying network information rather than the actual voice or data messages transmitted over the network.
CORBA - CORBA is an architecture and specification for creating, distributing, and managing distributed program objects in a network. It allows programs at different locations and developed by different vendors to communicate in a network through an "interface broker."
Cracker - Someone who breaks an encrypted computer code or circuitry.
Crusoe - Crusoe is a family of "smart" microprocessors from Transmeta that combines a relatively simple, low-powered hardware processor with software that makes the hardware processor look like an x86 Intel processor (such as a Pentium III). Because Crusoe requires only one-fourth of the usual number of transistors, the processor has a small power requirement.
CTIA - A trade group representing cellular, PCS and enhanced specialized mobile radio carriers.
