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.
Given disk blocks are 4 KB in size and a pointer to a disk block requires 4 bytes, answer the following questions. (Not: all answers have one decimal place only) a. What is the maximum size of a file that can be stored in this file system? ТВ b. What percentage of the required storage is overhead if the file is 100K bytes? 96 c.What percentage of the required storage is overhead if the file is 1000K bytes? 96

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 ?

Part B
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....
