A file system control block has the following address method: 10 direct block address, 10-bit single indirect address, and 10-bit double indirect address. The block size is 8K bytes. What address method will be used for the data files of 100K, 10M, and 10G bytes respectively? List the detailed computation to justify your answer.
Homework Answers
Disk blocks= 8K bytes
10 direct block address
8K*10= 80K can be accessed directly
Single indirect block: –
10‐bit address, we have 1 byte per block pointer,
so 8KB/1 = 8192 blocks –
Can access file size: 8192 * 8 KB = 64 MB
Double‐indirect block: –
Can access file size: 8192 * 8192 * 8 KB = 512

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 ?

Q1) A particular implementation of UNIX operating system provides the file structure modelled in the Figure 1. Here the i-node for the file contains certain information such as the access permissions for the file. This is followed by the entries that contain information about where the file is located on the storage device. The first 10 entries are the addresses of blocks where actual data for the file are stored. If block can contain 512 bytes of information, then these...
