Local Bus

In computer science, a local bus is a computer bus that connects directly, or almost directly, from the CPU to one or more slots on the expansion bus. The significance of direct connection to the CPU is avoiding the bottleneck created by the expansion bus, thus providing fast throughput. There are several local buses built into various types of computers to increase the speed of data transfer. Local buses for expanded memory and video boards are the most common.

VESA Local Bus is an example of a local bus design.

Although VL-Bus was later succeeded by AGP, it is not correct to categorize AGP as a local bus. Whereas VL-Bus operated on the CPU's memory bus at the CPU's clock speed, an AGP peripheral runs at specified clock speeds that run independently of the CPU clock (usually using a divider of the CPU clock).

Famous quotes containing the words bus and/or local:

    Nora was always free with it and threw her heart away as if it was a used bus ticket.
    Angela Carter (1940–1992)

    Back now to autumn, leaving the ended husk
    Of summer that brought them here for Show Saturday
    The men with hunters, dog-breeding wool-defined women,
    Children all saddle-swank, mugfaced middleaged wives
    Glaring at jellies, husbands on leave from the garden
    Watchful as weasels, car-tuning curt-haired sons
    Back now, all of them, to their local lives....
    Philip Larkin (1922–1986)
