Primary storage is the:

A.
Memory used in conjunction with real memory to present a CPU with a larger, apparent
address space.

B.
Memory directly addressable by the CPU, which is for the storage of
instructions and data that are associated with the program being executed.

C.
Memory, such as magnetic disks, that provide non-volatile storage.

D.
Memory where information must be obtained by sequentially searching from the beginning of
the memory space.

Explanation:
* Answer “Memory, such as magnetic disks, that provide non-volatile storage” refers to secondary
storage.
* Answer “Memory used in conjunction with real memory to present a CPU with a larger, apparent
address space” refers to virtual memory, and answer “Memory where information must be
obtained by sequentially searching from the beginning of the memory space” refers to sequential
memory.
