MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -They are often referred to as a guest while the physical machine they run on is referred to as the host. Virtualization makes it possible to create multiple virtual machines, each with their own operating system (OS) and applications, on a single physical machine. A VM cannot interact directly with a physical computer.

Detailed explanation-2: -A hypervisor is software that creates and runs virtual machines (VMs). A hypervisor, sometimes called a virtual machine monitor (VMM), isolates the hypervisor operating system and resources from the virtual machines and enables the creation and management of those VMs.

Detailed explanation-3: -A host virtual machine is the server component of a virtual machine (VM), the underlying hardware that provides computing resources to support a particular guest virtual machine (guest VM). Together, the host virtual machine and guest virtual machine make up a virtual machine server.

Detailed explanation-4: -System virtual machines The physical, “real-world” hardware running the VM is generally referred to as the ‘host’, and the virtual machine emulated on that machine is generally referred to as the ‘guest’. A host can emulate several guests, each of which can emulate different operating systems and hardware platforms.

Detailed explanation-5: -What Is Host Operating System? The host operating system is software on a computer that works with the underlying hardware. The term is typically used when differentiating from the guest operating system used in a virtualized server.
