Q. Illustration of cache size of a system?
Cache Size: Cache memory is very costly as compared to main memory and therefore its size is generally kept very small. It has been found by statistical studies that reasonably small caches can have a important impact on processor performance. As a typical illustration of cache size a system having 1 GB of main memory may have nearly 1 MB of cache memory. Most of today's personal computers have 64KB, 128KB, 256KB, 512KB or 1 MB of cache memory.
