- An operating system has a total of three user processes, and each of these processes uses a total of two units of the resource R. The total number of units that R is used up by the operating system is twelve. The absolute minimal number of R units that must be used to eliminate the possibility of any deadlocks happening isAn operating system contains 3 user processes, each process requiring 2 units of the resource R. The minimum number of units ofR required such that there is no possibility of deadlock on R is A 6 B 3 С 5 D 4There are a total of three user processes in an operating system, and each of these processes utilizes a total of two units of the resource R. The operating system consumes a total of twelve units of R, making this the total amount of units that are used up. The very bare minimum amount of R units that must be used in order to do away with the potential of any deadlocks occurring is

An operating system contains 3 user processes each requiring 2 units of resource R .The minimum number of units of R such that no deadlocks will ever arise is a. 4 b. 3 c. 5 d. 6
- For each of its three user processes, an operating system uses a total of two units of the resource R. A total of 12 units of R are used by the operating system. To ensure that there are no deadlocks, the bare minimum number of R units that must be used isAn operating system comprises three user processes, and each of these processes consumes two units of the resource R. The minimal number of R units that must be employed in order to avoid deadlocks isReal Time Scheduling: Select all statements below that are true EDF scheduling assigns the highest priority to a process with the smallest remaining time until its deadline. RM scheduling assigns a higher priority to processes with shorter periods. Rate Monotonic (RM) scheduling works by dividing the total amount of time available into an equal number of shares, and then each process must request a certain share of the total when it tries to start. If a process has period p, it is activated every p units of time. A real-time system is schedulable under Earliest Deadline First (EDF) when its overall CPU utilization is less than or equal to 1. A real-time system is schedulable under RM when its overall CPU utilization is less than 1.
- An operating system uses the banker’s algorithm for deadlock avoidance when managing the allocation of three resource types X, Y and Z to three processes P0, P1 and P2. The table given below presents the current system state. Here, the Allocation matrix shows the current number of resources of each type allocated to each process and the Max matrix shows the maximum number of resources of each type required by each process during its execution Allocation Max X Y Z X Y Z P0 0 0 1 8 4 3 P1 3 2 0 6 2 0 P2 2 1 1 3 3 3 There are 3 units of type X, 2 units of type Y and 2 units of type Z still available. The system is currently in safe state. Consider the following independent requests for additional resources in the current state- REQ1: P0 requests 0 units of X, 0 units of Y and 2 units of Z REQ2: P1 requests 2 units of X, 0 units of Y and 0 units of Z Write a program to check whether: Only REQ1 can be permitted Only REQ2 can be permitted…Multiprocessor systems use multiple CPUS to perform various tasks. This increases throughput and reduces response time. In this problem, a multiprocessor system has a certain number of processors. Each processor has the ability to schedule a limited number of processes in one second. However, after this scheduling, the processor's ability is reduced to floor(ability/2). Given the processor's abilities and the number of processes, what is the minimum time required to schedule all the processes in the system? Example n = 5 (number of processors and size of ability[]) ability = [3, 1, 7, 2, 4] processes = 15 This optimal solution is: 1. First, the processor with ability = 7 schedules 7 processes in one second. Now, ability = [3, 1, 3, 2, 4] because 7 was reduced to floor(7/2). There are 15 - 7 = 8 remaining processes. 2. Second, the processor with ability = 4 is used. After that, ability = [3, 1, 3, 2, 2]. Remaining processes = 8 - 4 = 4. 3. Third, a processor with ability = 3 is used.…An operating system uses the banker's algorithm for deadlock avoidance when managing the allocation of three resource types X, Y and Z to three processes P0O, P1 and P2.
