Define thrashing.
Thrashing is the accident of high page traffic and low CPU utilization. It is observed that the cause of thrashing is an under-commitment of memory to programs. The cure is to enhance the memory allocation for each program. This may perhaps have to be achieved by removing some programs from the memory that is by decreasing the degree of multiprogramming.
What are scheduling queues? Since the processes enter the system they are put into job queue. This queue contains all processes in the system. The processes that are exist in m
What is reference string We evaluate an algorithm by running it on a definite string of memory reference and computing the number of page faults. The string of memory reference
