How do you use this?!

Thank to Sir Tom our... ( I ran out of compliments because no words can describe the awesomeness of Sir Tom) teacher taught us how to use this!!

He said that this is a powerful tool in the computer world. He also said that it was removed because of people using it in bad ways. 

Sir Tom taught us only the basic(you know opening some folders and stuff). He also said that it can be used to hack (hehe). It was removed because of people out there in the world trying to hack something but in older versions of operating systems the command prompt still exists.

I want to know more on how to use the command prompt in various ways.

But I think that will take a little more time.

Wish me luck!
