MS-DOS

MS-DOS was one of the earliest operating systems on Earth. It makes use of simple command (and complex attributes) to operate. It is also uncomplicated, with only a few files that adds up to less than 1 mb.(compare it to Vista that wolf down gbs of space!) One thing I loves about dos is its simplicity whick keeps the errors down. There are no Bsod, software compatibility problems etc. Even nowadays, when there are great GUI featured Windows, dos is still needed.
