How long does it take for a person to context switch?

What happens after context switching?

In computing, a context switch is the process of storing the state of a process or thread, so that it can be restored and resume execution at a later point. This allows multiple processes to share a single central processing unit (CPU), and is an essential feature of a multitasking operating system.

How long does it take brain to switch tasks?
