what is the purpose of fat and ntfs system?

Answer 1

Without getting really technical it is difficult to truly answer that question. As far as what you will actually see as differences when you use them: NTFS supports files over 4GB, file by file compression and encryption while FAT does not. NTFS also provides better security than FAT.

Answer 2

FAT File Allocation Table

A table that the operating system uses to locate files on a disk. Due to fragmentation, a file may be divided into many sections that are scattered around the disk. The FAT keeps track of all these pieces.
In DOS systems, FATs are stored just after the boot sector.
The FAT system for older versions of Windows 95 is called FAT16, and the one for new versions of Windows 95 and Windows 98 is called FAT32.

NTFS NT FileSystem
(pronounced as separate letters) Short for NT File System, one of the file system for the Windows NT operating system. (Windows NT also supports the FAT file system). NTFS has features to improve reliability, such as transaction logs to help recover from disk failures. To control access to files, you can set permissions for directories and/or individual files. NTFS files are not accessible from other operating systems such as DOS.
For large applications, NTFS supports spanning volumes, which means files and directories can be spread out across several physical disks.

Answer 3

To install an operating system, the hard disk must be formatted to a file system.. two such file systems are NTFS and FAT.. only after creating a file system we can install an Operating System

Answer 4

They are filing systems for disk storage... they help computer operating systems find desired information on the disk... or store it...

FAT = File Allocation Table.. it is kind of like a list of where all of the files are stored.

I THINK NTFS stands for NT Filing System but I'm not sure what kind of format it takes.. it may be similar to FAT only able to handle larger files.

Answer 5

the computer can only read a disk serially. e.g like a series of letter(characters). the fat and ntfs filesystems define a specific order(a structure) of these characters that allow the computer to give you the standard paradigm of files -> folders -> subfolders -> etc. There are other filesystems too such as the ext2/ext3/ext4 filesystems, the reiser3/reiser4 filesystems, the BeFS filesystem, the HFS filesystem, and the XFS filesystem which is a super fast filesystem from SGI. there are also network file systems which allow you to access files over the network. these include NFS, AFS, DFS, GFS, and the new Hadoop Fs.

Answer 6

they're file storing systems for computing.
