When is the "thrashing" condition likely to occur in a system using virtual memory?

Thrashing occurs when a system has insufficient physical memory, causing excessive paging as the operating system continuously swaps data between RAM and disk. This leads to high overhead and severely degrades system performance, as more time is spent on paging rather than executing processes.
A computer is in System mode when: When does a deadlock occur in a system? Which memory management scheme allows the physical address space of a process to be non-contiguous? Which is better, Time slicing or time sharing? Why do modern operating systems use preemptive multitasking? What is the main purpose of a context switch in an operating system? Where is the Page Table typically stored in a computer system? When is the "thrashing" condition likely to occur in a system using virtual memory? How to resolve the critical section problem in concurrent programming? Which of the following are/is true? What mechanism does an operating system use to handle the execution of multiple processes that require frequent access to the CPU?
