The most frequently used instructions of a computer program are likely to be fetched from:
A. the hard disk
B. cache memory
C. RAM
D. registers
E. None of these
Answer: Option B
Solution (By Examveda Team)
Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory.This Question Belongs to Computer Fundamentals >> Computer Fundamental Miscellaneous
The most frequently used instructions of a computer program are likely to be fetched from Cache memory.
Cache memory, also called CPU memory, is high-speed static random access memory (SRAM) that a computer microprocessor can access more quickly than it can access regular random access memory (RAM). This memory is typically integrated directly into the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU. The purpose of cache memory is to store program instructions and data that are used repeatedly in the operation of programs or information that the CPU is likely to need next. The computer processor can access this information quickly from the cache rather than having to get it from computer's main memory. Fast access to these instructions increases the overall speed of the program.
Register bcoz its near to the cpu
