(A)-(II), (B)-(IV), (C)-(I), (D)-(III)
- B.
(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
- C.
(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
- D.
(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Attempted by 5 students.
Show answer & explanation
Correct answer: C
RAM temporarily holds the programs currently being executed, so A matches IV. DVD-ROM is treated in this PYQ as permanent optical storage written once and then read many times, so B matches III. ALU performs arithmetic, logic, computation and comparison operations, so C matches II. CPU controls processing and is called the brain of the computer, so D matches I. Therefore, the correct matching is (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
