    Cache (pronounced cash) memory is extremely fast memory that is built into a computer’s CPU, or located next to it on a separate chip. The CPU uses cachememory to store instructions that are repeatedly required to run programs, improving overall system speed. The advantage of cache memory is that the CPU does not have to use the motherbord's system bus for data transfer. Whenever data must be passed through the system bus, the data transfer speed slows to the motherboard’s capability. The CPU can process data much faster by avoiding the bottleneck created by the system bus.e memory in computer.[/quote]
