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.
