It allows the operating system to use one physical memory location for the storage of data that is currently being used by another process. This reduces the amount of time that the computer needs to access the physical memory to find the data that is needed.

vi /etc/fstabFollow the below example.
root@MinexVM ~ # free -m // View the current Swap settings (current system settings have 1162MB of virtual memory)

Swap: 1162 29 1133
root@MinexVM ~ # cat /proc/swaps // View the Swap mount location (the current system is set to /swapfile in the root directory)

root@MinexVM ~ # swapoff /swapfile // Stop Swap the swap partition (note the partition location)
root@MinexVM ~ # rm /swapfile // Delete Swap partition files
root@MinexVM ~ # vi /etc/fstab // Remove startup startup items
