FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Cache memory is an extremely fast memory type that acts as a buffer between RAM and the CPU. It holds frequently requested data and instructions so that they are immediately available to the CPU when needed. Cache memory is used to reduce the average time to access data from the Main memory.

Detailed explanation-2: -Most users are confused by the terms buffering and caching. Although they both temporarily store the data, they are not the same. Buffering is mainly used to match the communication speed between the sender and the receiver. On the other hand, cache improves the access speed to frequently used data.

Detailed explanation-3: -Cache memory is the fastest memory available and acts as a buffer between RAM and the CPU. The processor checks whether a corresponding entry is available in the cache every time it needs to read or write a location, thus reducing the time required to access information from the main memory.

Detailed explanation-4: -Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request. The name of the actual hardware that is used for cache memory is high-speed static random access memory (SRAM).

Detailed explanation-5: -Buffer memory is a temporary storage area in the main memory (RAM) that stores data transferring between two or more devices or between an application and a device.
