+Disk thrashing describes a state where a computer frequently accesses its [virtual memory](/wiki/virtual_memory) on a hard drive instead of [RAM](/wiki/RAM). This excessive data swapping between slow storage and fast memory overwhelms the system, leading to severe performance degradation. The CPU becomes bottlenecked, waiting for data transfers rather than executing tasks.
