A virtual machine (VM) is a software-based computer that exists within another computer’s operating system, often used for the purposes of testing, backing up data, or running SaaS applications. To grasp how VMs work, it’s important to first understand how computer software and hardware are typically integrated by an operating system. Assume that an operating system uses 500 MB of RAM to hold all of the running processes. However, there is now only 10 MB of actual capacity accessible on the RAM. The operating system will then allocate 490 MB of virtual memory and manage it with an application called the Virtual Memory Manager (VMM).
