Expert Solution

Step 1: Cache mapping

1) Cache mapping refers to the process of determining how data is stored and retrieved in a cache memory. It defines the relationship between the addresses of data in the main memory (RAM) and their corresponding locations in the cache.

2) The choice of cache mapping technique is a critical design decision in computer architecture, as it directly impacts the cache's performance characteristics, including hit rate, miss rate, and access time. Different applications and systems may benefit from different mapping techniques based on their specific memory access patterns and hardware constraints.
