See all on Wikipediahttps://en.wikipedia.org/wiki/Context_switchIn 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, and then restoring a different, previously saved, state. This allows multiple processes to share a single central processing unit (CPU), and is an … See more

- User and kernel mode switching "When a transition between user mode and kernel mode is required in an operating system, a context switch is not necessary; a mode transition is not by itself a context switch. However, depending on the operating system, a context switch may also take place at this time."A mode transition is not a context, but the con...
