In this area CPU can store its data temporarily, like the data to be forwarded to other slow-speed output devices or other secondary storage devices, to enable the computer to execute other processes. Cache Information that is used and accessed by most of the programs while running is stored in the cache to make them faster.By using the cache we can reduce the speed of memory access by a factor of 10. Therefore, Cache is the answer Special purpose register It is one that has a specific control or data handling task to carry out.
