How many sectors will a 125 KB file use in a FAT32 file system?

The correct answer is C. 250. In a FAT32 file system, the standard sector size is 512 bytes. To calculate the number of sectors required for a 125 KB file: 125 KB × 1,024 bytes/KB = 128,000 bytes. Dividing by the sector size: 128,000 ÷ 512 = 250 sectors. Therefore, a 125 KB file will occupy exactly 250…

Explanation

In a FAT32 file system, the standard sector size is 512 bytes. To calculate the number of sectors required for a 125 KB file: 125 KB × 1,024 bytes/KB = 128,000 bytes. Dividing by the sector size: 128,000 ÷ 512 = 250 sectors. Therefore, a 125 KB file will occupy exactly 250 sectors. This calculation assumes perfect alignment and no cluster overhead; in practice, the file would be rounded up to the nearest cluster boundary, but based on pure sector math, the answer is 250.
