Step 1: Definition of Terms.
- **Seek Time** (A): Time taken by the disk arm to move to the desired cylinder.
- **Access Time** (B): The total time taken to access a disk sector, including both seek time and rotational latency.
- **Rotational Latency** (C): The time taken for the disk to rotate and align the desired sector under the disk head.
- **Disk Bandwidth** (D): The rate at which data can be read or written from/to the disk.
Step 2: Match each term with the corresponding feature.
- **Seek Time** corresponds to **(IV)**, which is the time taken for the disk arm to move to the required cylinder.
- **Access Time** corresponds to **(III)**, which is the sum of seek time and rotational latency.
- **Rotational Latency** corresponds to **(II)**, which is the time for the disk to rotate the desired sector under the head.
- **Disk Bandwidth** corresponds to **(I)**, which refers to the rate of transfer of data.
Step 3: Conclusion.
The correct matching is **(A) - (I), (B) - (II), (C) - (III), (D) - (IV)**.
