Are you wondering what DOS is? Well, its simple, many many years ago before we all started getting the "BLUE screen" that we all have come to know and hate, there was a operating system named DOS. It was Microsoft's BIG seller. Its what made them what they are today and what computers are today.
 

Now you maybe asking yourself, "Great but I have Windows now! Why would I want to know DOS?" This is another simple question to answer, YOU STILL USE DOS DAILY! Unless you have Windows NT or Windows ME. But NT and ME STILL emulate DOS! Windows just sits on DOS and passes its commands back and forth to do functions. Its NOT a complete version of DOS but its about 80%! And believe it or not there are still computers with DOS on them!
