(f) Explain the following, giving their uses and advantages/disadvantages, if needed. (Word limit for answer of each part is 50 words ONLY) (i) Rotational Latency in disks (ii) Programmed I/O (iii) Resolution of Display and Printer (iv) Zip Drive (v) Power Supply (vi) Keyboard and Mouse

 (i) Rotational Latency in Disks:

   - Use: Time taken for the desired disk sector to rotate under the read/write head.

   - Advantage:  Helps optimize disk access by considering the rotational position.

   - Disadvantage: Variable and adds to overall access time.

(ii) Programmed I/O:

   - Use: Basic I/O method where the CPU controls data transfer.

   - Advantage: Simple implementation.

   - Disadvantage: CPU-intensive and inefficient for large data transfers.

(iii) Resolution of Display and Printer:

   - Use: Specifies the clarity/detail of visual output.

   - Advantage: Higher resolution offers better quality.

   - Disadvantage: Increased resolution demands more resources.

(iv) **Zip Drive:**

   - Use: Portable storage drive.

   - Advantage: Higher capacity than floppy disks.

   - Disadvantage: Limited popularity, overshadowed by other storage solutions.

(v) Power Supply:

   - Use: Provides electrical power to computer components.

   - Advantage: Stable power is crucial for system functionality.

   - Disadvantage: Susceptible to fluctuations and failures.

(vi) Keyboard and Mouse:

   - Use: Input devices for user interaction.

   - Advantage: Essential for user-friendly interface.

   - Disadvantage: Physical wear, limited input options compared to newer technologies.
