Match List-I with List-II $$ \begin{array}{|c|l|} \hline \textbf{List-I} & \textbf{List-II} \\ \hline (A)\ \text{Seek Time} & (I)\ \text{Total number of bytes transferred,} \\ & \ \ \ \text{divided by the total time} \\ & \ \ \ \text{between the first request for service} \\ & \ \ \ \text{and the completion of the last transfer} \\ \hline (B)\ \text{Access Time} & (II)\ \text{Time taken for the disk} \\ & \ \ \ \text{to rotate the desired sector} \\ & \ \ \ \text{to the disk head} \\ \hline (C)\ \text{Rotational Latency} & (III)\ \text{Seek Time + Rotational Latency} \\ \hline (D)\ \text{Disk Bandwidth} & (IV)\ \text{Time taken for the disk arm} \\ & \ \ \ \text{to move the heads} \\ & \ \ \ \text{to the cylinder} \\ & \ \ \ \text{containing the desired sector} \\ \hline \end{array} $$
Explanation:
(A) Seek Time: Time taken for the disk arm to move the heads to the cylinder containing the desired sector.
⇒ (A) → (IV)
(B) Access Time: Seek Time + Rotational Latency.
⇒ (B) → (III)
(C) Rotational Latency: Time taken for the disk to rotate the desired sector to the disk head.
⇒ (C) → (II)
(D) Disk Bandwidth: Total bytes transferred divided by total time between the first request and completion of last transfer.
⇒ (D) → (I)
∴ Correct matching is: (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
