MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -CPU cache is a bit of memory placed on the CPU. This memory operates at the speed of the CPU rather than at the system bus speed and is much faster than RAM. Disk cache holds recently read data and, sometimes, adjacent data areas that are likely to be accessed soon.

Detailed explanation-2: -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. This allows for faster processing as the processor does not have to wait for the data and instructions to be fetched from RAM.

Detailed explanation-3: -At the highest level, the most frequently used information-say, the instructions in a loop which execute repeatedly-is stored directly on a special section of the processor chip, called Level 1 (L1) cache. This is the fastest memory of all.

Detailed explanation-4: -The data most frequently used by the CPU is stored in cache memory. The fastest portion of the CPU cache is the register file, which contains multiple registers. Registers are small storage locations used by the CPU to store instructions and data.

Detailed explanation-5: -cache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer’s main memory.
