Question

Quizplus · Accepted Answer

Semaphores are a technique for controlling access to a critical region of code by using synchronization primitives. They are used to manage concurrent access to shared resources and ensure that only one process at a time can access the critical region. Spooling is a technique for managing input/output requests, time-sharing involves sharing of computing resources among multiple users, and booting is the process of starting a computer system. None of these techniques specifically address controlling access to a critical region.
