- What is thrashing in an operating system, and how can it be prevented?
Thrashing is when a system spends most of its time moving pages between RAM and disk instead of running programs, because the running processes together need more memory than is available. It is prevented by giving each process enough frames for its working set, controlling page-fault rate, and reducing the number of running processes.
