Five files have the following sizes (in bytes): 3 200, 7 800, 12 500, 2 050 and 9 600. The disk block size is 1 024 bytes.

- With linked allocation, each file occupies one block for each 1 024‑byte chunk of its data (the last block may be partially filled).
- With indexed allocation, each file also requires one additional index block of 1 024 bytes, in addition to the data blocks computed as above.

Calculate the total disk space (in bytes) required by the two allocation methods and state which method uses less space.

Five files have the following sizes (in bytes): 3 200, 7 800, 12 500, 2 050 and 9 600. The disk block size is 1 024 bytes.

Calculate the total disk space (in bytes) required by the two allocation methods and state which method uses less space.

Accepted Answer

Linked allocation uses 38 912 bytes (less than indexed allocation's 44 032 bytes).
