Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

____ allows multiple operating systems to run on a single hardware device at the same time by more efficiently using system resources, like processors and memory.

A	Full virtualization
B	Paravirtualization
C	Partial virtualization
D	process virtualization

Explanation:

Detailed explanation-1: -Portability: Hypervisors allow multiple operating systems to reside on the same physical server (host machine). Because the virtual machines that the hypervisor runs are independent from the physical machine, they are portable.

Detailed explanation-2: -Virtualization software-programs that allow you to run multiple operating systems simultaneously on a single computer-allows you to do just that. Using virtualization software, you can run multiple operating systems on one physical machine.

Detailed explanation-3: -Paravirtualization is a type of virtualization where software instructions from the guest operating system running inside a virtual machine can use “hypercalls” that communicate directly with the hypervisor. This provides an interface very similar to software running natively on the host hardware.

Detailed explanation-4: -OS virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. The technology got its start on mainframes decades ago, allowing administrators to avoid wasting expensive processing power.
