FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Cache memory is important because it improves the efficiency of data retrieval. It stores program instructions and data that are used repeatedly in the operation of programs or information that the CPU is likely to need next.

Detailed explanation-2: -Cache memory is a type of high-speed random access memory (RAM) which is built into the processor . Data can be transferred to and from cache memory more quickly than from RAM. As a result, cache memory is used to temporarily hold data and instructions that the processor is likely to reuse.

Detailed explanation-3: -Cache memory holds frequently used instructions/data which the processor may require next and it is faster access memory than RAM, since it is on the same chip as the processor. This reduces the need for frequent slower memory retrievals from main memory, which may otherwise keep the CPU waiting.

Detailed explanation-4: -A cache’s primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Trading off capacity for speed, a cache typically stores a subset of data transiently, in contrast to databases whose data is usually complete and durable.
