Detailed explanation-1: -In computer science, thrashing occurs when a computer’s virtual memory resources are overused, leading to a constant state of paging and page faults, inhibiting most application-level processing. This causes the performance of the computer to degrade or collapse.
Detailed explanation-2: -How does virtual memory work? Virtual memory uses both the computer’s software and hardware to work. It transfers processes between the computer’s RAM and hard disk by copying any files from the computer’s RAM that aren’t currently in use and moving them to the hard disk.
Detailed explanation-3: -A process is said to be thrashing if the CPU spends more time serving page faults than executing the pages.
Detailed explanation-4: -In computer science, thrashing occurs when a computer’s virtual memory resources are overused, leading to a constant state of paging and page faults, inhibiting most application-level processing. It causes the performance of the computer to degrade or collapse.
