Answer: Caches are useful when two or more components need to exchange data, and the components perform transfers at differing speeds. Caches solve the transfer problem by providing a buffer of intermediate speed between the components.

What is cache memory and its types?

Memory Caches. … Two types of caching are commonly used in personal computers: memory caching and disk caching. A memory cache (sometimes called a cache store, a memory buffer, or a RAM cache) is a portion of memory made up of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM).
