local bus

hardware A bus connecting a processor to memory,

usually on the same circuit board as opposed to a

backplane and therefore faster.

Various proprietary local busses for personal computers are

still in use. The most common are Vesa local bus (VLB or

VL), and Peripheral Component Interconnect (PCI). Some

computers, e.g. notebook computers, use a local bus with no

expansion slots. Previous non-local bus standards include

ISA, EISA and MCA.
