UGC NET December 2023 Re-Exam (14.12.2023) Shift-I
In the computer memory hierarchy, arranged from the fastest and smallest at the top (I) to the slowest and largest at the bottom (IV), which memories represent positions I, II, III and IV in that order? Choose the correct answer from the options given below.
- 1. Magnetic Tape
- 2. Magnetic hard disk
- 3. Random access memory
- 4. Processor registers
A4, 3, 1, 2
B1, 2, 3, 4
C2, 3, 4, 1
D4, 3, 2, 1 ✓ Correct
Correct answer: (D) 4, 3, 2, 1 — From fastest to slowest the order is processor registers, RAM, hard disk, magnetic tape, so the answer is 4, 3, 2, 1.
Explanation
★From fastest to slowest the order is processor registers, RAM, hard disk, magnetic tape, so the answer is 4, 3, 2, 1.
★The memory hierarchy ranks storage by speed, cost and capacity.
★Processor registers are the fastest and smallest, sitting inside the CPU.
★Random access memory is next, holding data and programs in current use.
★The magnetic hard disk is slower secondary storage with large capacity.
★Magnetic tape is the slowest, cheapest storage used for backup and archiving.
