A Comparison of File Systems

Submitted To: Madam Sulema Submitted By: UMAR MOIN USMAN RAUF Subject: Operating System Class: Bs (CE)-5A

Introduction: In computing, a file system is a method for storing and organizing computer files and the data they contain to make it easy to find and access them. File systems may use a storage device such as a hard disk or CDROM and involve maintaining the physical location of the files, they might provide access to data on a file server by acting as clients for a network protocol (e.g., NFS, SMB, or 9P clients), or they may be virtual and exist only as an access method for virtual data (e.g. procfs).

Objectives/Scope: The objective is to study and understand the way Windows and Linux File Systems work and to differentiate between them on the basis of their features. We will try to study the following file systems: • FAT-16 • FAT-32 • NTFS • ReiserFS • Ext2 • Ext3 • XFS

Methods: The following methods will be used to illustrate the topic : • Charts • Tables • Graphs • Simulation • Existing Research Papers(Optional/might or might not be done)
