Of the following, which is the fastest?
Verified Answer
A. CD-ROM
B. RAM
C. Registers
D. Cache
E. None of these
Explanation:
In the computer memory hierarchy, registers are the fastest memory components, located directly within the CPU, used to hold data that the CPU is actively processing. Cache memory is faster than RAM but slower than registers. RAM (main memory) is slower than cache. CD-ROM is a very slow optical storage device.
