MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In the case of fully associative mapping, The main memory block is capable of mapping to any given line of the cache that’s available freely at that particular moment. It helps us make a fully associative mapping comparatively more flexible than direct mapping.

Detailed explanation-2: -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.

Detailed explanation-3: -Direct mapping:-Direct mapping is the very simplest technique because in which every block of primary memory is mapped into the single possible cache line. In Direct mapping, every memory block is allotted for a particular line in the cache memory.

Detailed explanation-4: -Fully Associative Mapping refers to a technique of cache mapping that allows mapping of the main memory block to a freely available cache line. Also, a fully associative cache would permit the storage of data in any cache block. There would be no forcing of every memory address into a single particular block.

Detailed explanation-5: -Fully Associative Mapping-In fully associative mapping, A block of main memory can map to any line of the cache that is freely available at that moment. This makes fully associative mapping more flexible than direct mapping.
