A file of size 2000 KB is stored on a disk whose block size is 4 KB. (a) If the file is stored contiguously, the read time is 5 ms per block plus 0.01 ms per KB of data transferred. (b) If the same file is fragmented into 5 non‑contiguous fragments, an additional seek time of 2 ms is incurred for each fragment. Which storage method yields the shorter total read time? State the total read time for each method and indicate the faster one.

Answer Options

A. Contiguous: 2500 ms, Fragmented: 2550 ms - contiguous is faster
Correct Answer B. Contiguous: 2520 ms, Fragmented: 2530 ms - contiguous is faster
C. Contiguous: 2530 ms, Fragmented: 2520 ms - fragmented is faster
D. Contiguous: 2600 ms, Fragmented: 2600 ms - both are equal
Correct Answer
B
Correct Option:
Contiguous: 2520 ms, Fragmented: 2530 ms - contiguous is faster
