Is context switching time and dispatch latency same?

Dispatcher is used for changing state of process from ready to running. So I would guess dispatch latency is the amount of time required to change state from ready to running, for a particular process. In context switch on the other hand, kernel running in context on a process stops and starts running in context of another process.

I might be wrong.

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.

Dispatch Latency includes context switch time but also the time for the dispatcher to chose a process.

Storing state of a process $\subseteq$ kernel stops running in context of one process and starts running in context of another. Correct me if I’m wrong.
