If you are concerned about how many bytes per second your computer can transfer from main memory to the CPU, what part of the computer should you investigate to determine this figure?
A) the data bus and external clock speed
B) the Level I cache and internal clock speed
C) the size of the CPU registers
D) the address bus and the external clock speed

Question

The data bus width and the external clock speed directly influence the rate at which data can be transferred from the main memory to the CPU. The data bus width determines how much data can be moved at once, and the external clock speed affects how quickly these transfers can occur.
