Virtual Machines (VMs)

A virtual machine (VM) is a software-based version of a physical computer that runs within a host computer's operating system. It allows multiple VMs to operate independently on the same hardware, each with its own virtual hardware, operating system, and applications. Think of a VM as a separate, self-contained computer inside a computer, enabling users to run different operating systems or software environments without needing additional physical machines. VMs are widely used for testing, development, server hosting, and isolating applications for security and management reasons.
