What are the requirements for a swapper to work, Operating System

 

The swapper works on the biggest scheduling priority. Initially it will look for any sleeping process, if not get then it will see for the ready-to-run process for swapping. But the major need for the swapper to work the ready-to-run process must be core-resident for at least 2 seconds before going out. And for swapping in the process must have been resided in the swap machine for at least 2 seconds. If the need is not satisfied then the swapper will go into the wait state on that event and it is activated once in a second by the Kernel.
