Windows 2000 Server
1. Windows 2000 is more robust and reliable than Windows NT .
2. CHKDSK works much faster with Windows 2000 than with Windows NT.
3. Windows 2000 clusters are more reliable than Windows NT clusters.
4. The method that Windows NT uses to manage disk volumes makes it difficult to share volumes between different operating systems.
5. Overall, Windows 2000 offers advantages for disk volume management compared to Windows NT.
6. Using the Distributed File System (DFS) to virtualize disk space works poorly in Windows NT. It works better and is supported in Windows 2000.
-The new Virtual Disk Service (VDS)
-Volume Shadow Copy Service (VSS)
-Multipath I/O (MPIO)
-Boot from SAN
-The volume-mounting function
-The Check Disk command,
-The Distributed File System(DFS)
-The Encrypting File System (EFS),

Microsoft Disk operating system.
MSDOS stands for Microsoft Disk operating system.
MS-DOS is a non-graphical command line 16-bit operating system.
MSDOS created for IBM compatible computers that were first introduced by Microsoft in August 1981.
Last updated in 1994 when MS-DOS 6.22 was released.
The command shell more commonly known as the Windows command line is still used.
MS-DOS does not use a mouse
The command interpreter is integrated in the file COMMAND.com with the internal commands for MS-DOS. The file IO.sys for simple device routines like the access to the monitor, keyboard, fixed storage disks and interfaces. The and MSDOS.sys for the booting code these form the base operating system.
MS-DOS 5.0 use of the High Memory and Upper Memory Area, TSR programs and drivers. The most new external commands in this version are DOSKEY, DOSSHELL, EDIT, EMM386 and LOADHIGH. UNDELETE can recover deleted files, UNFORMAT can undo the format of floppy disks. 2.88 mb floppy disk drives from IBM are now supported.
MSDOS Internal commands
del, erase/delete, rd/rmdir, dir, cd/chdir, cls, md/mkdir, copy, ren/rename, type, set, ver, vol,
MSDOS External commands
attrib, chkdsk, format, fdisk, deltree, diskcopy, diskcomp, edit, doskey, defragment, move, mem, tree, etc.
System environment
- minimum: 512 KB RAM, 5 MB harddisk storage (depends on version for full installation)
- FAT file system
- executable with every x86 compatible CPU
- low RAM and fixed storage disk needs
