Question

To run multiple operating systems on a single machine, which of these is needed?
firmware
multitasker
hypervisor
OS switcher

Answer 1

To run multiple operating systems on a single machine, you need a **hypervisor**.

A hypervisor is a layer of software that allows multiple operating systems to run on a single physical machine by managing the hardware and allocating resources to each OS. There are two main types of hypervisors: Type 1 (bare-metal) and Type 2 (hosted).

While firmware, multitaskers, and OS switchers are relevant concepts in computing, they do not specifically refer to the capability to run multiple operating systems concurrently on the same hardware.

So, the correct answer is **hypervisor**.
