What is Cache?

Explanation:
Cache is a small, very fast storage area that holds data and instructions the CPU is likely to reuse soon. Because it sits close to the processor and uses fast memory, it cuts the time the CPU spends waiting for data from the main memory. When the processor needs something, it first checks the cache; if the data is there, the operation proceeds quickly, which speeds up processing overall. If it isn’t, the data is fetched from RAM (or further) and then stored in the cache for future use. This makes cache different from RAM, which is larger but slower, and from a hard drive or BIOS, which serve different roles in the system. So the description “temporary storage area designed to help speed up processing time” is exactly what cache is.
