1). Well, at a time only one thread is allocated the CPU in multithreaded application. If you are saying that your thread is regularly busy with I/O, then practically it can happen that all other threads keep waiting in queue to get CPU allocated to them. It depends upon the CPU
allocation algorithmused. Like if thread are usingTime-Sharingalgorithm, then of course on completion of time, current thread will be send to the back of the queue.2). Check out this post: – Difference between binary semaphore and mutex
