Question
A unix-style I-node has 10 direct pointers and one single, one double and one triple indirect pointers. Disk block size is 1 Kbyte, disk block address is 32 bits, and 48-bit integers are used. What is the maximum possible file size?
|
A |
224 bytes |
|
B |
232 bytes |
|
C |
234 bytes |
|
D |
248 bytes |
Solution:
Option (C) is Correct.
Maximum size of file = 10 Direct + 1 Single Indirect + 1 Double Indirect + 1 Triple Indirect
= 10 + 28 + (28)2 + (28)3
= 224 Blocks (App)
Size of each block = 210
Maximum file size = 224 × 210 = 234
