What is file-allocation table (FAT) and what is free-space list ?
Homework Answers
file-allocation table (FAT) : A system through the contents of hard drive which an operating system keeps over a hard drive.(or) A table which an operating systems employed for locating the files over a disk.
free-space list : usually the operating sytems sustains a list of free space for maintaining the track of each and every disk block which were unused through a particular file.

Operating System Problem Three file allocation techniques for storing a file on disk, namely contiguous allocation, linked allocation, and indexed allocation. For each allocation method show how a file of 10 blocks would be allocated on disk. Note that the disk is represented as 30 blocks with blocks 0, 5, 6, 15, 25 already allocated. Note you must show the entire data structure for each allocation method as part of the answer. Thanks
