Question

Quizplus · Accepted Answer

A cache is a small amount of very fast memory located on or near the CPU. Its purpose is to store frequently-used data and instructions, providing faster access to this information than can be obtained from the main memory or from external storage devices such as hard drives. Options A, B, and C are not accurate descriptions of CPU memory. The main memory, for example, is larger than the cache and not as fast; a data channel and serial bus are communication pathways used by different computer components, not types of memory.
