Acronym for Communication and Networking Riser. Developed by Intel, CNR is a riser card for ATX family motherboards that was developed in order to reduce the cost to OEMs of implementing LAN, home networking, audio and modem subsystems widely used in modern connected PCs. The CNR Specification is an open industry specification that defines a scalable motherboard riser card and interface that support the audio, modem, and network interfaces of core logic chipsets. The specification is supported by OEMs, Microsoft and silicon suppliers. The specification defines the CNR architecture for both standard and low-profile risers and includes electrical, mechanical, and thermal requirements of the riser interface. In addition to supporting current technologies such as Ethernet and analog modems, the specification can be expanded for developing technologies, such as DSL.
Short for central office. In telephony, a CO is a telecommunications office centralized in a specific locality to handle the telephone service for that locality. Telephone lines are connected to the CO on a local loop. The CO switches calls between local service and long-distance service. ISDN and DSL signals also channel through the CO.
Short for Cache on a Stick, a cache technology developed by Intel. COAST is a small circuit board with cache SRAM chips that is attached to a motherboard, increasing the computer’s L2 cache. The circuit board is inserted into a special socket on the motherboard called a CELP.
- Common Business Oriented Language (COBOL)
Acronym for common business oriented language. Developed in the late 1950s and early 1960s, COBOL is the second-oldest high-level programming language (FORTRAN is the oldest). It is particularly popular for business applications that run on large computers. COBOL is a wordy language; programs written in COBOL tend to be much longer than the same programs […]
Short for Constructive Cost Model, a method for evaluating and/or estimating the cost of softwaredevelopment. There are three levels in the COCOMO hierarchy: Basic COCOMO: computes software development effort and cost as a function of program size expressed in estimated DSIs. There are three modes within Basic COCOMO: Organic Mode: Development projects typically are uncomplicated […]
Short for Conference on Data Systems Languages, and pronounced code-a-sill, an organization founded in 1957 by the U.S. Department of Defense. Its mission was to develop computer programming languages. CODASYL was responsible for developing COBOL. The organization is no longer extant, but the term CODASYL is still used sometimes to refer to COBOL.
