A PC, by definition, is a computer that runs Windows.
Windows XP natively supports FAT12, FAT16, FAT32, and NTFS. Other file systems, such as HPFS, JFS, ext2/3, and ReiserFS can be supported through an IFS (Installable File System).
For personal use the big ones are Windows and Leopard for MacOS (Apple computers). There are a number of Linux flavors which exist. Another OS is ReactOS. That is a free, open source clone of Windows, though it has a long ways to go. There's a full list of Operating Systems on Wikipedia. Search "list of current operating systems"
DOS 1.x and 2.x: These ancient DOS versions support only the FAT12 file system, used today primarily for floppy disks. If you're still using DOS 1.x or 2.x, man do you need a new computer! :^)DOS 3.x through 6.x: These are more common versions of DOS for older PCs running either straight DOS or Windows 3.x. DOS 6.x was especially popular; millions of copies of these operating systems were sold. DOS 3.x through 6.x support the older FAT12 and the newer FAT16, which was the file system standard for many years in the PC world.DOS 7.0: MS-DOS 6.22 was the last "standalone" version of DOS sold by Microsoft. After DOS6.22, Microsoft sold DOS only as the underpinnings of other operating systems, such as Windows 95/98/ME. The first of these was MS-DOS 7.0, which runs "underneath" the first Windows 95 version (Windows 95A). It supports FAT12, FAT16 and VFAT, the enhanced version of FAT that includes support for long file names.DOS 7.1 and later: These versions of DOS underlie Windows versions from Windows 95 OEM Service Release 2 (Windows 95B) and later. They support FAT12, FAT16, VFAT and FAT32.
Windows Server operating systems offer cloud computing built into the OS, and a good solution for other windows systems is the online based Windows Live SkyDrive.

It is the brand name of Microsoft series of operating systems (e.g. windows 3.1, windows 95, windows 98, windows 98 second edition, windows 2000 windows xp, windows vista). Operating systems like Microsoft windows provides a framework that allow other software that can run on it, to be able to interact with each other, the computer hardware and the user who is using the computer
Meridian and NEC both sell office telephone systems.
Windows NT is the foundation for all current Windows Operating Systems. Windows XP, Vista, Workstation, and 7 all use the NT foundation. Windows ME was the other attempt at creating a stable Operating System foundation for future use, but it failed.

Microsoft-based operating systems such as Windows Server 2003, Windows XP, Windows Vista, and Windows 7 starting to come out now are the most popular. After that, other operating systems include Macintosh OSX, variations of unix, including Linux, and depending on the application, mainframe operating systems such as OS/400 and Solaris.--Greg
