A computer runs a round-robin process scheduler with system contention scope and for a while there are 4 CPU-intensive processes in the system, without doing any I/O operations. What is the percentage of the CPU utilization allocated to each process? Write just the percentage number, without the % sign. For example. If the answer is 50% write 50, not 50% or 1/2. What statements about processor affinity are true? It prevents a process from migrating (its execution) to another processor It reduces the number of context switches. It adversely impacts the scheduler overhead It increases the number of cache hits for accesses to min memory. On a single-CPU system in steady state with 10 processes, the average waiting time is 0.5 seconds. What is the average arrival rate for new processes in the queue? write just the rate number: e.g., if the answer is 5 processes/second. write just 5 With preemptive scheduling it is possible to preempt a process while executing a system call and in kernel mode? True False
