    Cache (pronounced cash) memory is extremely fast memory that is built into a computer’s central processing unit (CPU), or located next to it on a separate chip. It is used by CPU 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 motherboard’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.

    It is a kind of temporary memory , which is responsible for the fast execution of data from the CPU and RAM, as the CPU cannot work as fast a RAM does. so its helps CPU to respond faster.
