Consider a file system that uses inodes to represent files. Disk blocks are 4-KB in size and a pointer to a disk block requires 4 bytes. This file system has 12 direct disk blocks, plus two single indirect disk blocks. What is the maximum size of a file that can be stored in this file system? A single indirect disk block points to a block where its whole space is used to point to data blocks. Please explain it as well. Thanks!
Homework Answers
- In the main file system Single, Double triple indirect blocks are more size as compare to Direct block. To store the data, required more space. So, indirect blocks allow to use whole space for Data Blocks.

Consider a file system that uses inodes to represent
files. This file system has 16 direct disk blocks, as well as
single, double, and triple indirect disk blocks. This file system
is illustrated in the below figure. Please notice that the tables
pointed to by the indirect pointers are full sized blocks that only
stores pointers.

A UNIX-type file-system uses a disk block size of 1KB, 128 byte inodes, and 32 bit disk addresses. If the inode contains 64 bytes of data, 8 direct, 1 indirect, 1 double-indirect, and 1 triple- indirect blocks, apart from other file information. How many disk blocks would be required for storing files of sizes (a) 1 byte (b) 1024 bytes (c) 64 KB (d) 1MB ?
