What is the maximum file size supported by a file system with 16 direct blocks, a single, a double, and a triple indirection blocks? The block size is 1KB. Disk block numbers can be stored in 4 bytes.

Computer Science Operation System question. I will give thumb
up, thank you!
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.

Consider a file system that uses inodes to represent files. To locate the physical blocks of each file, its inode contains up to 12 direct disk blocks, as well as one single, one double, and one triple indirect disk blocks. a. If disk blocks are 1 KB in size, and a pointer to a disk block requires 4 bytes. What is the maximum size of a file that can be stored in this file system? Note the size of a...
Consider a file system that uses 1KB blocks and 16-bit disk addresses. If inodes hold 8 disk addresses for data blocks, one single-indirect block address, and one double-indirect block address. What is the maximum file size?
Given a Ext3 filesystem that uses: - 32 bit addresses, - 512 byte blocks on disk, - 16 direct addresses and - up to a level 3 indirection Answer the following questions: 1) How many blocks does a 12KiB file need? 2) What is the largest file size (in KiB) that does not need indirect block references? 3) What is the largest file size (in KiB) possible using only single indirection? 4) A file that is 1104 bytes in size,...
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 ?
11. Consider a file system that uses a structure similar to an i-node with the following differences. If the file size is less than 100 bytes, the data is stored directly in the i-node. If it is larger, there are 6 direct links (point to a data block), 1 single-indirect links, 2-double indirect links and 1 triple indirect link. (a) What is the largest file size that can be indexed in this system? Assume the block size is 512 bytes....

Consider a file system that uses a structure similar to an i-node with the following differences. If the file size is less than 100 bytes, the data is stored directly in the i-node. If it is larger, there are 8 direct links (point to a data block), 2 single-indirect links, 1-double indirect links and 1 triple indirect link. What is the largest file size that can be indexed in this system? Assume the block size is 1024 bytes....
Operating System: In a combined UNIX UFS file system, with single, double and triple indirect pointers, answer the following: a) what is the maximum possible size of a file? Assume that a pointer takes 4 bytes and that blocks are 128 bytes long. b) In a file of maximum size, what is the ratio of storage in bytes consumed by all the pointers and pointer blocks to the maximum file size in bytes?

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...
STORAGE AND FILE SYSTEM • Example 9-A 32-bit Berkeley UNIX file system has a block size of 8 kilobytes. How many blocks of a given file can be accessed: • (a) Using the block addresses stored in the i-node? blocks • (b) With one level of indirection? blocks _blocks • (c) With two levels of indirection?
