A unix file system has 1-KB blocks and 4-byte disk addresses. What is the maximum file size if i-nodes contain 10 direct entries and one single, double and triple indirect entry each?
Correct Answer: D — 16 GB
Explanation:
With 1 KB blocks and 4-byte addresses, each block holds 256 addresses. The triple indirect block contributes 256 × 256 × 256 × 1 KB = 16 GB, which heavily dominates the maximum file size limit.
