Answer 2

The "effectiveness of the cache memory" is based on the property of "Average Access Time".

Explanation:

The cache is a critical part of most of the high-performance computers. The performance of the cache is measured based on the cache hits and the cache misses.

Cache hits mean the number of accesses that actually find that data in the cache, whereas cache misses means those that do not find the data in the cache. These cache hits and misses contribute to the term Average Access Time (AAT) also known as Average Memory Access Time (AMAT).
