Which emulated system has dedicated CPU, memory, storage, and a full operating system installed?

A virtual machine (VM) is an emulated computer system that runs on a physical host. It includes its own dedicated virtual CPU, memory, storage, and a complete operating system (OS), independent of the host OS. This isolation allows multiple VMs to run concurrently on a single physical server without interfering with each other. A mainframe is a high-performance computer used for large-scale data processing, not an emulated system. A host is the physical server that provides resources for VMs or containers. A container shares the host OS kernel and resources, providing process-level isolation rather than full OS virtualization like a VM.
