What are buffer and cache memory?

Answer by  john11 (617)

Cache memory is specialized memory that serves as a temporary holding location. There are two components that use this: hard-drive and CPU. CPU cache allows CPU to quickly access recent data or instructions without accessing slower RAM. Hard-drives use cache as a location to retrieve and send data via RAM.

Buffer memory is a temporary storage location for something you're going to use later. If you add 1 and 2, the result, 3, will be stored on a buffer until you need it. Cache is simply memory that gets accessed more often than others, it's faster for better performance.

Basically smaller memory areas that are much faster than the rest of your RAM. They have very limited storage, but are much faster because of it.

Cache memory is in between the RAM and the processor,Cache reduces the access time of processor.Buffer is register memory that is very faster and costlier than cache.
