What is virtual memory management
The Linux Information Project defines virtual memory management as the process by which a computer uses hard drive space to simulate extra random access memory, or RAM, thereby tricking the system into thinking it has more memory available to it than it actually does.BenefitsVirtual memory management allows programs to run even if the machine lacks the necessary RAM. The result is fewer programs that will not launch, and fewer system freezes due to a lack of available resources.DrawbacksThe resulting virtual memory is much slower than physical RAM and can cause added wear on the hard drive. The fluctuation in size of the virtual memory space can also make it difficult for a user to accurately determine the amount of free hard drive space left on the drive.CustomizationOn most operating systems, the computer will automatically adjust the size of virtual memory space based on the amount of memory needed, and the amount of available hard drive space; however, the size of virtual memory ca
