Virtual machines (VMs) are software-based representations of physical computers that can run applications and operating systems just like a physical machine. They allow multiple operating systems to run on a single physical machine, enabling users to run different applications and workloads on the same hardware.
VMs are commonly used in enterprise environments for server consolidation, testing and development, and disaster recovery. They provide flexibility and scalability, as well as cost savings by reducing the need for physical hardware.
VMs are created and managed using virtualization software, which allows users to allocate resources such as CPU, memory, and storage to each VM. This enables organizations to optimize their infrastructure and utilize resources more efficiently.
Overall, virtual machines play a crucial role in modern computing environments by providing a flexible and efficient way to run multiple operating systems and applications on a single physical machine.
