Git

Git is what people in the programming world called a Version Control System, or VCS for short. To put it in a nutshell, Git makes your code traceable for changes, revisions, and makes simultaneous real time collaboration a whole lot less painful. So, the next time someone asks you to put your code on a Cloud Drive, go ahead and kick them hard.

GitHub, on the other hand, is an online, Ruby based platform that provides Git hosting as a service.
