A. Magnetic tape
B. Magnetic disk
C. Optical disk
D. All of the above
Check Answer
The correct answer is A) Magnetic tape.
Primary storage devices, also known as internal or main memory, are used to store data and instructions temporarily during processing. The data stored in primary storage devices can be accessed quickly by the CPU.
Magnetic disk and optical disk are examples of primary storage devices because they are used to store data and instructions temporarily during processing.
On the other hand, magnetic tape is a secondary storage device that is used to store large amounts of data for archival purposes or backup. It is not used for temporary storage during processing, and hence, it is not a primary storage device.
Therefore, option A (Magnetic tape) is NOT a primary storage device, and option D (All of the above) is incorrect.
