non-volatile
longer storage capacity
lower price per bit
faster E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is D. faster.
Disk is slower than main memory because it is a mechanical device that has to move its read/write heads to access data, while main memory is a solid-state device that can access data much faster.
A. Non-volatile means that data is not lost when power is turned off. Disk is non-volatile, while main memory is volatile.
B. Longer storage capacity means that disk can store more data than main memory.
C. Lower price per bit means that disk is cheaper per bit of storage than main memory.
