Answer 1

File System:

In computing, a file system (often also written as filesystem) 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 data storage device such as a hard disk or CD-ROM 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). It is distinguished from a directory service and registry.



More formally, a file system is a special-purpose database for the storage, organization, manipulation, and retrieval of data.

________



File Allocation Table or FAT is a computer file system architecture now widely used on most computer systems and most memory cards, such as those used with digital cameras.



It was developed by Bill Gates and Marc McDonald during 1976–1977.[1][2] It is the primary file system for various operating systems including DR-DOS, FreeDOS, MS-DOS, OS/2 (v1.1) and Microsoft Windows (up until Windows Me). For floppy disks, it has been standardized as ECMA-107[3] and ISO/IEC 9293. Those standards include only FAT12 and FAT16 without long filename support; long filenames with FAT is partially patented.



The FAT file system is relatively straightforward technically and is supported by virtually all existing operating systems for personal computers. This makes it a useful format for solid-state memory cards and a convenient way to share data between operating systems.

_______



NTFS is the standard file system of Windows NT, including its later versions Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista, and Windows 7.



NTFS supersedes the FAT file system as the preferred file system for Microsoft’s Windows operating systems. NTFS has several improvements over FAT and HPFS (High Performance File System) such as improved support for metadata and the use of advanced data structures to improve performance, reliability, and disk space utilization, plus additional extensions such as security access control lists (ACL) and file system journaling. The file system specification is a trade secret, although it can be licensed commercially from Microsoft through their Intellectual Property licensing program.

Answer 2

File system is a data structure or a collection of files.In UNIX it is in the form of directory tree or the arrangement of files on disk partitions. The latter can be thought of as the physical filesystem as it has a tangible physical location



NTFS file system as the preferred file system for Microsoft’s Windows operating systems.



File Allocation Table - (FAT) is suitable for an MS-DOS or Windows 95 file system which describes the files, directories, and free space on a hard disk or floppy disk.

Answer 3

The harddisk can store an arbitrary binary content, it's just 01001010 all the way from start to end.



To put an order to this dump of mess, the OS writes and reads data in a systematic manner according to the filesystem it uses. The filesystem is this read/write system that describes how to store data (the file itself) and all its metadata (like where it is stored, the fragmentation table, readonly/system/archive flags, etc). That way, instead of a bunch of binaries, the OS can see the harddisk as files and folders structure.



That's of course, is simplified from the real thing but you should get the rough idea.

Answer 5

File system is a way for saving and ordering computer files and the date(collection of fact and figures) they contain to make it easy easy to find and access them. File system can use data storage device like a hard disk

Answer 6

nah its just the way the OS manages your files NTFS are mainly used this days Fat 32 have some advantage but having a 3 gb limit no way!

Answer 7

SYSTEM FILES: these are those files which are essential to run your computer. with our these files ur computer will not run properly



NTFS AND fat32: this is a format of ur hard disk.LIKE IF ur hard disk of 10gb and in ntfs fromat and after converting ur ntfs disk into fat32 ur diskspae will b increasd bt ur hard is is safe in ntfs format. FAT32 IS NOT SAFE
