Which pairing is correct?.
- A.A wider address bus can address more memory locations, while a wider data bus can transfer more bits at once
- B.A wider address bus transfers more data per cycle, while a wider data bus addresses more memory locations
- C.A wider address bus increases the number of cores, while a wider data bus increases clock speed
- D.A wider address bus increases cache capacity, while a wider data bus increases word length
Model answer
What a good answer should say
- A wider address bus can address more memory locations, while a wider data bus can transfer more bits at once
Explanation
Why this works
The address bus carries addresses, so increasing its width increases the range of memory locations that can be addressed. The data bus carries data, so increasing its width allows more bits to be transferred in one operation.
