What is a critical section of code? Group of answer choices A section of code that can be executed by multiple threads simultaneously. A section of code that must be executed atomically by a single thread at a time. A section of code that is not executed by any thread. A section of code that is always executed by the main thread.

All processes share a semaphore variable mutex, initialized to 1. Each process must execute wait(mutex) before entering the critical section and signal(mutex) afterward. Suppose a process executes in the following manner: signal(mutex), critical section wait(mutex), In this situation: a deadlock will occur processes will starve to enter the critical section several processes may be executing in their critical section all of the mentioned

A race condition occurs when two or more threads can access shared data and they try to change it concurrently. Because the kernel can swap between threads at any time, you don't know the order in which the threads will attempt to access the shared data. In the following, we will create a program that stores a global variable, global, initialized to 0.We also create two pThreads that attempt to access the shared variable. thread1 is a thread that increments global 90,000,000 times, while thread2 concurrently decrements global the same number of times. 1. What is the expected value of global when both threads have finished executing?
