Navigating the World of Virtual Machines in Operating Systems

A virtual machine is a software-based emulation of a physical computer that operates and executes programs like a physical machine. It runs on a host machine and acts as a separate computer system with its own operating system and applications. Virtual machines are commonly used for testing software compatibility, running multiple operating systems on a single physical machine, and creating isolated environments for security purposes. They offer flexibility, scalability, and cost savings compared to physical machines.
