Describe how the computer bus affects the speed of a computer?

BUS speed is used to define how fast data can be copied from one area of the computer to another. The BUS speed can relate to data being moved between memory and the processor, for example. A processor can process at it's peak speed, but the BUS defines how fast the computer can FEED the processor. Two identical processors, one with a 533 mhz FSB and one with an 800 mhz FSB, the 800 mhx FSB will pass data to the processor faster.
