Detailed explanation-1: -Memory-mapping is a mechanism that maps a portion of a file, or an entire file, on disk to a range of addresses within an application’s address space. The application can then access files on disk in the same way it accesses dynamic memory.
Detailed explanation-2: -Three distinct types of mapping are used for cache memory mapping: Direct, Associative and Set-Associative mapping.
Detailed explanation-3: -Explanation: This happens in the associative mapping. In this case, a block of data from the main memory can be mapped anywhere in the cache memory.
Detailed explanation-4: -Direct mapping is a procedure used to assign each memory block in the main memory to a particular line in the cache. If a line is already filled with a memory block and a new block needs to be loaded, then the old block is discarded from the cache.
