A disk has 100 sectors. Each sector is 512 bytes, and the cluster size is 4 sectors. What is the maximum file size that can be stored on this disk?

  1. A.

    20,480 bytes

  2. B.

    40,960 bytes

  3. C.

    51,200 bytes

  4. D.

    409,600 bytes

Show answer & explanation

Correct answer: C

Correct answer: 51,200 bytes

  • Sector size: 512 bytes.

  • Cluster size: 4 sectors = 4 × 512 = 2,048 bytes.

  • Number of clusters: 100 sectors ÷ 4 sectors per cluster = 25 clusters.

  • Maximum file size: 25 clusters × 2,048 bytes = 51,200 bytes.

The same result is obtained by using the total disk capacity directly: 100 × 512 = 51,200 bytes.
