Disk thrashing definition computer science
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. The situation can continue … See more Virtual memory works by treating a portion of secondary storage such as a computer hard disk as an additional layer of the cache hierarchy. Virtual memory is notable for allowing processes to use more memory than is physically … See more Thrashing is best known in the context of memory and storage, but analogous phenomena occur for other resources, including: See more • Page replacement algorithm – Algorithm for virtual memory implementation • Congestion collapse – Reduced quality of service due to high network traffic • Resource contention – Conflict over access to a shared resource See more Webcache memory, also called cache, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer. The cache augments, and is an extension of, a computer’s main memory. Both main memory and cache are internal random-access memories (RAMs) …
