Question

Quizplus · Accepted Answer

The capacity of a memory module can be calculated by multiplying the number of memory banks by the storage capacity of each bank. In the case of a 256x72 DIMM, the module has 256 memory banks and each bank has a capacity of 72 bits.

Converting 72 bits to bytes: 
1 byte = 8 bits 
72 bits = 9 bytes

So, the total capacity of the DIMM is: 
256 banks x 9 bytes per bank = 2,304 bytes

Converting 2,304 bytes to gigabytes: 
1 GB = 1,073,741,824 bytes 
2,304 bytes = 0.00214748 GB

Therefore, the capacity of a 256x72 DIMM is 2GB, which is best represented by answer choice D.
