You have more RAM than you've ever expected

RAM is the acronym of Random Access Memory and every computer have RAM installed in it but have you wondered why your RAM can handle more than the memory that is installed on your unit? That's what Virtual Memory comes. In your device whether it's mobile or computer it has a builtin virtual RAM in it where it supports the physical RAM that process all of your running applications.

If you ask me the question "Why can't I just use the Virtual Memory without the physical RAM?".
Well, virtual memory is installed into your HDD "Hard Disk Drive" and the job of virtual memory is to support the physical Random Access Memory only! You can adjust your virtual memory if it's needed by going to your system settings then look for virtual memory.
