These will all show up from time to time during various aspects of working with Linux, so it is important to know what these are and what they are used for. EXT2: EXT2 is a traditional Linux file system. It supports permissions on the individual user level. However, it has been largely replaced by newer versions of this file system. EXT2 is a non-journaling file system. EXT3: EXT3 is an updated version of EXT2. Like its predecessor it supports permissions on the individual user level. However, its major improvement is that EXT3 is a journaling file system, thus making it faster for startup times and recovery. Reiser: Reiser or ReiserFS is a journaling file system that is very similar to EXT3. However, its design makes it more suited for use with databases than EXT3. FAT: FAT or File Allocation table, is a file system developed in the late 70's. It is a file system that is universally compatible with virtually all operating systems, making FAT and its successors (FAT16 and FAT32) very popular for use on Flash drives and other media that may need to share data between multiple operating systems. NTFS: NTFS or New Technology File System is a proprietary Microsoft file system developed for NT 4.0 and Windows 2000. It is commonly found on all major Windows Operating systems developed after the year 2000 including Windows XP, Windows 2003, and Windows 7. While most Linux distros can't write to NTFS, some of the more popular distros such as Ubuntu are capable of both reading and writing to NTFS. VFAT: VFAT is a variation on the DOS FAT file system that supports long file names. ISO9660: ISO9660 is the file system used for accessing data on CDs. It originated from the International Standards Organization recommendation 9660. Network: In addition to the 7 local file systems above, you should also be aware of the following network file systems: NFS: NFS or Network File System is a protocol that was developed by Sun Microsystems. It is used to allow other computers to remotely access data over a network. SMBFS/CIFS: SMBFS/CIFS relates directly to an application-layer network protocol known as Server Message Block. It is used to provide shared network access to files, printers, and other miscellaneous communication between network nodes. This is most frequently used with Microsoft Windows.
