what is swapping,virutual memory
During data processing operating systems use the hard disk as memory. It is called the virtual memory. During processing, operating system transfers some amount of data from RAM to hard disk and reloads again when required. The operating system exchanges the data and programs between RAM and hard disk. The data or programs are stored in hard disk in temporary file called the swap file. The word “swap” means exchange. This technique of swapping data between memory and hard disk is called paging.Os spends some amount of time in paging process by bringing the pages to ram.
