MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Software virtualization: Software virtualization creates a computer system complete with hardware that allows one or more guest operating systems to run on a physical host machine.

Detailed explanation-2: -When a single physical computer runs a special program known as virtualization software, it operates as though it were two or more separate and independent computers, known as virtual machines.

Detailed explanation-3: -A hypervisor, also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing.

Detailed explanation-4: -Virtualization relies on software to simulate hardware functionality and create a virtual computer system. This enables IT organizations to run more than one virtual system – and multiple operating systems and applications – on a single server. The resulting benefits include economies of scale and greater efficiency.

Detailed explanation-5: -Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host.” A thin layer of software called a “hypervisor” decouples the virtual machines from the host and dynamically allocates computing resources to each virtual machine as needed.
