local bus

(hardware)A bus connecting a processor to memory,usually on the same circuit board as opposed to abackplane and therefore faster.

Various proprietary local busses for personal computers arestill in use. The most common are Vesa local bus (VLB orVL), and Peripheral Component Interconnect (PCI). Somecomputers, e.g. notebook computers, use a local bus with noexpansion slots. Previous non-local bus standards includeISA, EISA and MCA.

Also called the "system bus," a local bus is the pathway between the CPU, memory and peripheral controller chips. The term was popular in the early 1990s with the introduction of the VESA local bus (see VL-bus). See bus and PC data buses.

Peripheral controller cards plug into slots on the local bus.
