Explanation

Primary storage refers to memory directly accessible by the CPU, including ROM and RAM. PROM (Programmable Read-Only Memory) is a type of ROM used as primary storage. Magnetic drums and floppy disks are secondary storage devices (also called auxiliary storage or external memory) because they are not directly accessible by the CPU without I/O operations.
