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.
List three ways of allocating storage, and give advantages of each. a. Contiguous allocation. Fastest, if no changes are to be made. Also simplest for random access files. b
