Cache Memory

Cache Memory. Historically, CPUs have always been faster than memories. In order to have a memory as fast as a CPU it must be located on the CPU chip. This makes the chip bigger and more expensive.

Cache?

Cache?. What is caching? A way to increase the average rate of a process by preferentially using a copy of data in a faster, closer, probably more expensive location instead of the data’s original, more distant, slower, less expensive location.
