Difference between git & github

1. git is a tool <--> github is a website (github.com)
2. git is Command line interface(CLI) <--> github is Graphical user interface(GUI)
3. we can't view data in bare repo <--> but we can view & do all actions in bare repo
4. bare is bare only here <--> but, bare repo you can convert into non-bare here
5. here we are creating non-bare by cloning bare repo <--> but, directly we can create/init non-bare
6. local <--> remotely
