Question

a) Threads fly-back time
b) Jitter
c) Context switch time
d) None of the mentioned

Answer 1

The time required to synchronously switch from the context of one thread to the context of another thread is called context switch time.

Step-by-step explanation:

The time required to synchronously switch from the context of one thread to the context of another thread is called context switch time. During a context switch, the operating system saves the current state of the executing thread and restores the saved state of the thread that is ready to run. This involves swapping out the register values, stack pointers, and program counters.

For example, if a processor is executing Thread A and it receives an interrupt or a preemption event, it must save the current state of Thread A and restore the state of a different thread, such as Thread B. This switch in execution from Thread A to Thread B is known as a context switch and has some overhead associated with it.
