Every computer is designed to have some initial o.s. Normally is DOS OPERATING SYS. Before installing anything in the system we need it. Initially we install or execute everything in this O.S. All commands are also executed under it. Even to install windows also we have to take help of DOS os. But when we install any other o.s then with it we automatically install upgraded version of DOS which will run under the installed os for better performence. So when ever we type any command under windows DOS then it will execute in dos but under windows control.
