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.

When thrashing occurs?
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.

How do you reinstall CD and DVD devices on a laptop?
Cd and DVD are auto detect by operating system.

how to rectify samsung hard disk. detect BIOS don't detect another system for slave hard disk. then, not installed os.
How do I uninstall your operating system to install a new system?
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.
How disc drive detect blank disc?
The disk drive doesn't. The operating system determines that there are no files on the disk.
What is thrashing with reference to Operating System?
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.

What architecture defines options for adding firmware and hardware to computers to detect low-level tampering before the operating system starts?
TPM
What is thrashing in computer terminology?
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.
