if your computer has a slow disk drive and you are doing a lot of paging (using virtual memory) to switch from one program to another rapidly, then your disk drive will become a performance bottleneck and your computer will seem to have trouble keeping up with your commands. The computer, here, is "thrashing", spending all of it's time trying to keep up. Imagine a person drowning. They are thrashing because they are spending all of their energy doing one thing to stay alive.

There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.
1. BATCH PROCESSING operating system 2. MULTIPROGRAMMING operating system 3. TIME SHARING operating system 4. REAL TIME operating system 5. DISTRIBUTED operating system

thrashing
Thrashing is computer activity that makes little or no progress, usually because memory or other resources have become exhausted or too limited to perform needed operations. When this happens, a pattern typically develops in which a request is made of the operating system by a process or program, the operating system tries to find resources by taking them from some other process, which in turn makes new requests that can't be satisfied. In a virtual storage system (an operating system that manages its logical storage or memory in units called pages), thrashing is a condition in which excessive paging operations are taking place.

There is no uninstaller for an operating system. To remove an OS, simply format the partition that holds the operating system. If you use a boot manager to choose between different operating systems the software should automatically detect missing operating systems for you.
The disk drive doesn't. The operating system determines that there are no files on the disk.
It is a phenomenon in virtual memory schemes when the processor spends most of its time swapping pages, rather than executing instructions. This is due to an inordinate number of page faults.

Thrashing is a high paging activity. A process is thrashing if it is spending more time with paging rather than execution.Thrashing is caused by under allocation of the minimum number of pages required by a process, forcing it to continuously page fault. The system can detect thrashing by evaluating the level of CPU utilization as compared to the level of multiprogramming.Caused by:-Global replacement algorithm.Under allocation of the minimum number of pages required by a process.Very high degree of multiprogramming.Eliminated by:-Reducing level or degree of multiprogramming.Use local replacement algorithm.While allocating check minimum sufficient frame required for a process.
