Different ways in which a thread can be cancelled, Operating System

Assignment Help:

What are the different ways in which a thread can be cancelled?

Cancellation of a target thread may happen in two different scenarios:

Asynchronous cancellation: One thread immediately terminates the target thread is known as asynchronous cancellation.
Deferred cancellation: The target thread can periodically check if it should terminate, permitting the target thread an opportunity to terminate itself in an orderly fashion.
