Question

Deallocation of stack of thread and register contexts will take place.

• A. at the termination of thread
• B. at the time of thread blocking
• C. at the time of thread spawning
• D. at the time of unblocking the thread

Hint:

Deallocation of resources occurs when a thread finishes its execution, which involves freeing up memory and other resources associated with the thread. This typically happens at the thread’s termination.

Answer 1

The Correct Option is A

A thread's stack and its register context are deallocated upon its termination. Deallocation involves freeing resources, such as memory and registers, that were allocated during the thread's execution. This process occurs only when the thread terminates, not during blocking, spawning, or unblocking, as these are temporary states where resources remain in use. Thus, the correct answer is: (1) at the termination of thread.
