GATE | GATE-CS-2014-(Set-2) | Question 65
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 x 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 ____________.
(A) 99.55 to 99.65
(B) 100.5 to 101.4
(C) 97.2 to 98.5
(D) 89.1 to 91.2
Answer: (A)
Explanation:
Here block size is 10^3 B.
No. of entries in the FAT = Disk capacity/ Block size
= 10^8/10^3
= 10^5
Total space consumed by FAT = 10^5 *4B
= 0.4*10^6B
Max. size of file that can be stored = 100*10^6-0.4*10^6
= 99.6*10^6B.
So answer 99.6.
