Question

Suppose the cluster size of a FAT system is 4 sectors, and we have created a text file of 900 bytes. What is the size of the file on disk?

Answer 1

Answer:

Given that:

Suppose the cluster size of a FAT system is 4 sectors, and we have created a text file of 900 bytes. What is the size of the file on disk?

in FAT system the files are allocated on the sectors.

Disk has clusters and these clusters are divided into sectors.

so if our file size is 900 byte then it's logical size is still 900 byte but what is the physical size of the disk?

generally one sector contains 512 bytes so for 900 bytes we need minimum 2 sectors which is 1024 byte

so on the disk this file will take 2 sectors.

The remaining space is know as slack space which 124 bytes.

so answer is 2 sectors which is 1024 bytes

and slack space is 124 bytes..
