If a computer uses 16 bits to specify an address in RAM, then the number of addresses will be
A2 raised to 16
B65,536
C64K
DAny of the above ✓ Correct
Correct answer: (D) Any of the above — Each of the given forms equals the same count, so the answer is any of the above.
Explanation
★Each of the given forms equals the same count, so the answer is any of the above.
★With 16 address bits, the number of addresses is 2 raised to the 16th power.
★Working this out gives 65,536.
★In computing, 64K also means 64 times 1024, which is 65,536.
★So all three forms name the same number.
★So the answer is any of the above.
