Cache Memory

Cache Memory in Computer Architecture

Cache Memory is in between the main memory and CPU. when we want to search any data, if it is available in cache memory then we easily fetch the data from cache memory otherwise we fetch those data from main memory.when the data is not available in cache memory then fetching the data from main memory is time consuming  process so when fetching the data from main memory we also make a copy of same data in cache memory so in future when we need a same data we easily fetch it from the cache memory, no need to go in the main memory.

Advantage:

1. Time Saving.
2. High Speed.
3. More Flexible.
4. More Versatile.
5. More Scalable.
