What is the function of a virtual machine?
A virtual machine (VM) functions as a software emulation of a physical computer, allowing multiple operating systems to run on a single hardware system. VMs operate inside a hypervisor, which allocates hardware resources like CPU, memory, and storage to each instance. This setup enables flexible and efficient utilization of physical resources. VMs are commonly used for development, testing, and deployment environments, providing a safe space to test software without affecting the underlying system. They also enhance scalability and resource management in cloud computing environments.
