What Is Cache Memory Definition?
Cache is the small amount of memory that is normally less then 1MB that resides on the CPU so that the time to access the main memory is reduced. Cache memory stores the copies of the most frequently used data and when the user requests to access a certain portion of the maim memory, the computer will check cache memory first and load it immediately if it is resent in the cache memory thereby reducing the access time. If it is not present in cache then it will load from the main memory and this involves latency.
