Deadlocks: Select all of the following statements that are true. A deadlock means that at least two processes cannot continue working because they are waiting for each other. One of the four introduced deadlock conditions is circular wait. Deadlock prevention aims to abort processes or preempt some resources when deadlocks are detected. If a resource-allocation graph is expedient, a knot is a sufficient condition for deadlock. The banker's algorithm's goal is to completely reduce the Maximum Claim Graph (MCG) given.
