Right Answer is: A
SOLUTION
Concept:
- The maximum number of bytes directly addressable in a computer depends on the number of bits in the memory address.
- For an n-bit address bus, the memory can store:
M ≤ 2n Bytes, since an 8-bit represents a byte.
Calculation:
Given Address bus = 8-bit
A maximum number of bytes the memory can store will be:
M = 28 Bytes
M = 256 Bytes
A typical representation of memory locations for an 8-bit address bus is as shown:
