Temp data: - Helps to maintain data when you move from one controller to other controller or from one action to other action. In other words when you redirect, "tempdata" helps to maintain data between those redirects. It internally uses session variables.

View data: - Helps to maintain data when you move from controller to view.

View Bag: - It's a dynamic wrapper around view data. When you use "Viewbag" type casting is not required.
