core - Computer Definition
- The central or essential part of a Wide Area Network (WAN) or Metropolitan Area Network (MAN) is commonly known as the core, or backbone. The network core comprises very high capacity elements and subsystems such as transmission systems, multiplexers, switches, and routers. See also MAN and WAN.
- The central and primary light-conducting portion of a glass optical fiber (GOF). The core is the inner portion of the fiber into which the optical signal is injected by either a light-emitting diode (LED) or one of many types of laser diodes. A single-mode fiber (SMF) used in a high speed, long haul fiber optic transmission system (FOTS) has a very narrow inner core, 5
(1) The heart, or central part, of something. The core of a network is its backbone. A core program would be the primary routines that serve the entire application (see kernel).
(2) In digital electronics, it typically refers to a relatively large, general-purpose logic function that is used as a building block in a chip design. Examples are microprocessor, microcontroller and DSP cores. Cores may be developed internally, but are generally purchased from third-party intellectual property (IP) vendors. See soft core and hard core.
(4) (Core) A family of CPU chips from Intel. Introduced in 2006, the Core line was developed to supersede the Pentium brand. See Intel Core.
(5) A round magnetic doughnut that represents one bit in an earlier core storage system. When core storage was common in the 1960s, a computer's main memory used to be called "core." See core storage.
