[amp_mcq option1=”semaphore” option2=”mutual exclusion” option3=”multiprogramming” option4=”multitasking E. None of the above” correct=”option2″]<\/p>\n
The correct answer is: B. mutual exclusion<\/strong><\/p>\n Mutual exclusion is a property of concurrent systems that ensures that only one process can access a shared resource at a time. This is necessary to prevent data corruption and ensure that the system runs correctly.<\/p>\n Semaphores are a synchronization primitive that can be used to implement mutual exclusion. A semaphore is a variable that can hold a value of 0 or 1. When the value of a semaphore is 0, it means that the resource is in use and no other process can access it. When the value of a semaphore is 1, it means that the resource is available and any process can access it.<\/p>\n Multiprogramming is a technique that allows multiple programs to run on a single computer at the same time. This is done by switching between the programs very quickly, so that it appears that they are all running at the same time.<\/p>\n Multitasking is a technique that allows a single program to run multiple tasks at the same time. This is done by dividing the program into multiple threads, which can run independently of each other.<\/p>\n None of the above options are correct.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”semaphore” option2=”mutual exclusion” option3=”multiprogramming” option4=”multitasking E.
