Original sentence: As a result CPU utilization drops even further, and CPU scheduler tries to increase the degree of multiprogramming even more.As a result, the effective memory-access time increases.If the CPU utilization is too low, The OS increase the degree of multiprogramming by introducing new processes to the system.It starts faulting and taking frames away from other processes.No work is being done.These processes need those pages, however, and so they also fault, taking frames away from other processes.Thrashing has occurred, and system throughput plunges
Edited sentence: As a result CPU utilization drops even further, and the CPU scheduler tries to increase the degree of multiprogramming even more.If the CPU utilization is too low, The OS increases the degree of multiprogramming by introducing new processes to the system.It is at this point, no further tasks can be performed on the system and the system 'locks' or 'freezes'.It starts faltering and taking frames away from other processes.Lastly, as a result, the effective memory-access time significantly increases.These processes need those pages, however, and so they also falter, taking frames away from other processes.Thrashing has therefore, said to have occurred, and system throughput subsequently plummets
