What is Bus Contention?
Bus Contention: A loss of performance that can arise when two or more devices – for example computer
PROCESSORS or disk controllers - try to transfer data simultaneously
over the same BUS. For example hesitation may be introduced into a video
or audio playback whenever the disk is being accessed. Contention is
ameliorated by some kind of ARBITRATION scheme that regulates bus usage
in a fair and orderly way, ensuring that all the contending devices are
granted access for a reasonable duration and within a reasonable time
..It can be avoided altogether by changing the hardware architecture so
as to provide separate buses for each device.
