ITPEC IP October 2023 Question 17
Which of the following is an appropriate explanation of the virtualization of a server?
Explanation
Running two or more virtual computers on one physical computer — that is server virtualization.
Virtualization software (a hypervisor) divides one physical server's CPU, memory, disk and network among several virtual machines, each running its own OS and applications as if it were a separate computer. Fewer physical servers are needed, which saves space, power and cost, and a virtual machine can be moved to another host.
Answer (c)
Why not others:
- •(a) — a computer-generated world users can interact with is virtual reality (VR)
- •(b) — operating a remote computer's GUI from a local one is remote desktop
- •(d) — using part of auxiliary storage to provide more memory than main memory has is virtual memory
Key rule: Server virtualization turns one physical machine into several logical ones; the word “virtual” in VR, remote desktop and virtual memory names different techniques.
