The difference between CMD and DOS

The DOS that you enter in the Windows operating system (that is, input CMD into the command prompt) is not pure DOS, but is built to facilitate certain requirements,
and pure DOS itself is an operating system. The difference between the two: for example, you can delete your Windows system under pure DOS,
but not in what you call "command prompt," because you can't "demolish a house inside a house?")

DOS is the disk operating system, the command prompt is the DOS system interface to enter the DOS command prompt location, CMD is the XP system running its own DOS command. 

DOS system you must use DOS language to achieve the use of the computer, WindowsXP, Vistia, 7 these have beautiful, friendly interface, use than DOS system simple, can use mouse click Control, and can not DOS command dos


is the early computer operating system. is a single-tasking single user and can only execute one program at a time. The interface is always constant text interaction ..... Commands are required for all operations. such as CD xx (enter xx named folder), dir list directory, CLS clear screen and so on. Windows that need to remember a lot of commands
is the graphical interface operating system. Multi-tasking multi-user. You can execute multiple programs at the same time. We can listen to the internet while listening to music, while watching the movie while hanging QQ, but the multi-tasking also brought security risks, easy in the virus. But Windows is simple, most operations need only a mouse click to complete, no longer need a large number of commands, so popular, so that ordinary people are easy to learn to use the computer.
but DOS has his advantage, fast response is no doubt, the most important is that DOS some commands are unique, remote operation and so on are required DOS command. And after Windows poisoning, the recovery system, copy data are done under DOS. (Of course, it is now gradually replaced by the graphic interface of PE.) The
difference: The dos that runs cmd out of Windows is not real DOS, that is Microsoft in Windows Virtual DOS environment, used to run some advanced commands, the real DOS is out of the system. Because he is an operating system.
