A virtual machine (VM) is a software-based emulation of a physical computer that runs an operating system and applications. It allows you to run multiple operating systems on a single physical machine, enabling you to consolidate hardware resources and run different software environments on the same hardware.
VMs are commonly used for testing software, running applications in isolated environments, and optimizing hardware usage in data centers. They provide a flexible and cost-effective solution for organizations looking to maximize the efficiency of their computing resources.
VMs are created and managed using virtualization software, such as VMware, VirtualBox, or Hyper-V. These tools enable users to create, configure, and manage VMs, allocate resources, and monitor performance.
Overall, virtual machines offer a convenient way to run multiple operating systems and applications on a single physical machine, making them a valuable tool for developers, IT professionals, and organizations looking to streamline their computing infrastructure.
