ITPEC IP April 2020 Question 11
ITPEC IP April 2020 — Question 11 of 100
Only statement I is correct. A 64-bit CPU can theoretically address a much larger memory space than a 32-bit CPU because its address representation can contain more distinct values.
Answer (a)
Why not others:
- many 64-bit processors can run a compatible 32-bit operating system, so II is false
- USB read and write speed depends on the USB standard, controller, device, and workload; changing CPU bit width does not automatically double it, so III is false
Key rule: CPU bit width affects instruction and address capabilities, but it does not impose a fixed multiplier on peripheral performance.
