What is a small unit of ultra-fast memory that is used to store recently accessed or frequently accessed data so that the CPU does not have to retrieve this data from slower memory circuits such as RAM?
A) ROM
B) Cache memory
C) Volatility
D) Flash memory

Question

Quizplus · Accepted Answer

Cache memory is designed to speed up the process of accessing data by storing copies of frequently accessed or recently accessed data from the main memory (RAM), allowing the CPU to access this data more quickly than if it had to retrieve it from slower memory circuits. ROM is read-only memory, not used for temporary storage of frequently accessed data. Volatility refers to a memory's ability to retain data when power is turned off, not a type of memory itself. Flash memory is a type of non-volatile storage that can be electronically erased and reprogrammed, but it is not specifically designed to act as a fast cache between the CPU and main memory.
