Git is a mildly insulting term denoting a silly or foolish person. Git is also a distributed revision control, software management program created by the developer of the Linux kernel Linus Torvalds.
GitHub while it may be used by the former, has to do with version control. It’s a repository for git services and collaboration. Ruby on Rails, Merb and RSpec use it; it’s popular amongst programmers for its functionality and social networking like attributes. GitHub allows users to easily fork projects, create new repositories and monitor development. Their pricing scheme targets both large enterprises and open source developers who haven’t got tons of funding. The free package comes with 100MB disk space and allows for an unlimited number of collaborators.
