A computer cache refers to a separate register file that acts as temporary and secondary memory during computer calculations and operations. The cache's purpose is to make data that is more frequently accessed in the course of a program readily available. The cache works by storing the value in a slot in its file register, with newer values replacing older and less used ones. Cache hit rate refers to the percentage of calls to the cache that are successful in retrieving the desired data.
