L-3.8: Semaphores | Wait, Signal Operation | Counting Semaphore | Example| Operating system

Описание: Semaphore is a variable that is non-negative and shared between threads. A semaphore is a signaling mechanism, and a thread that is waiting on a semaphore can be signaled by another thread. It uses two atomic operations, 1) Wait, and 2) Signal for the process synchronization. In this video, Varun sir will introduce Semaphore in detail in a simplest way possible. #operatingsystem
