Virtual Machines: A Game-Changer for Developers and IT Professionals

A virtual machine (VM) is a software-based emulation of a physical computer that runs an operating system and applications. It allows multiple operating systems to run on a single physical machine, providing a way to create isolated environments for different applications or testing purposes. Virtual machines are commonly used in cloud computing environments, development and testing environments, and for software compatibility testing. They offer flexibility, scalability, and cost-efficiency compared to running multiple physical machines.
