How does system detect thrashing?
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.
What happens when the computer is thrashing?
Thrashing occurs when a computer's virtual memory subsystem is in a constant state of paging, rapidly exchanging data in memory for data on disk, to the exclusion of most application-level processing. This causes performance of the computer to degrade and collapse.

What does excessive disk thrashing indicate?
You don't have enough RAM.Thrashing is the Operating Systems way of allowing programs larger than can fit in RAM function. It does this by temporarily swapping portions of programs, or entire programs in and out of RAM.Since programs can only run from RAM, when an OS switches between programs, and there isn't enough RAM, it has to grab programs from memory and put them into ROM. And the program needing to run in ROM has to be loaded in RAM.Another solution is to have a RAM Disk (hard to find and expensive, currently DDR2 only...as of 2012) or Solid State Hard Drive. Thrashing still occurs. But thrashing becomes fast enough that it is not very noticeable. It does cause wear on the Solid State Hard Drive.
What is thrashing and how it will be overcome?
when there are too many processes available and memory is low, than processor remains busy in swapping in and out the pages from disk in order to overcome it: 1) increase memory 2) reduce multi programming level
