Question

Only three operations may be performed on a semaphore: initialize, increment, and ________.

A) Wait
B) Signal
C) Lock
D) Release

Answer 1

The third operation on a semaphore, aside from initialize and increment, is wait. Semaphores are crucial for managing concurrent processes in computing.

Step-by-step explanation:

The third operation that can be performed on a semaphore, in addition to initialize and increment, is wait. The correct answer to your question is A) Wait. Semaphores are synchronization tools used in programming to manage concurrent processes in a multitasking environment.

The 'initialize' operation sets the semaphore to a certain value, 'increment' (or signal) increases the semaphore's value, and 'wait' decreases the semaphore's value, which may cause the thread to block if the semaphore's value is zero, indicating that a resource is unavailable.
