A FAT (file allocation table) based file system is being used and the total overhead of each entry in the FAT is 4 bytes in size. Given a 100 × 106 bytes disk on which the file system is stored and data block size is 103 bytes, the maximum size of a file that can be stored on this disk in units of 106 bytes is ___________.
-
- 11.6 × 105 B
- 9.6 × 106 B
- 99.6 × 106 B
- 19.6 × 103 B
Correct Option: C
| Number of Entries in the FAT = | = | = 105 | ||
| Block size | 103 |
Total space consumed by FAT = 105 × 4B = 0.4 × 106 B
Maximum size of the file that can be stored = 100 × 106 – 0.4 × 106 = 99.6 × 106 B
