Why paging is used in memory management

Hello Jenny,

Well paging is basically used to access the data faster and also when there are memory issues with your system and hard disks Paging helps. Especially when you are running so many processes in the system, here every process needs separate virtual spaces and also many a times when you use application that needs more memory space than in that case you need to use the Virtual memory. The virtual memory is also larger in size then the actual physical memory given in the system. Hope it helps,

Thanks!!

Why paging is used in memory management

Hi,

 

The paging or making use of a page file is used by the operating system to have a temporary storage for files, data or information. This allows the operating system to make use of your hard drive as a secondary storage for cases wherein the data would not fit in the available physical memory (Random Access Memory). This allows for a larger available memory. When the application tries to load information that is not yet on the physical memory, the operating system will try and load the information from the temporary storage. This process is slow as read/write on a hard drive takes longer compared to RAM. Therefore, if a system has a large amount of memory, there would be no need to use the page file consequently resulting to faster processing of data.

 

Thank you. Hope this helps.
