Understanding Virtual Machines and Emulation

What is a virtual machine?

• A physical computer system.

• An emulation of an existing computer system.

• A type of virtual memory.

• A hardware device.

What is the role of the host OS in a virtual machine setup?

• It runs within the virtual machine.

• It controls the physical hardware.

• It is emulated by the virtual machine.

• It is the same as the guest OS.

Which of the following best describes emulation?

• Running software directly on compatible hardware.

• Using an app/device to imitate the behavior of another program/device.

• A process of virtualizing memory.

• A method of increasing physical storage.

What is a guest OS?

• The main operating system of a computer.

• An OS running on a virtual machine.

• An OS that controls the physical hardware.

• An OS that is not compatible with the hardware.

Why is it important not to confuse virtual memory with virtual machines?

• They are the same concept.

• They serve different purposes and functions.

• Virtual memory is a type of virtual machine.

• Virtual machines are a subset of virtual memory.

In the context of the prompt, what would be an example of using a virtual machine?

• Running Windows software on a Windows PC.

• Running Apple software on a Windows PC.

• Running Linux software on a Linux PC.

• Running Android apps on an Android phone.

What does the emulation allow the Apple software to do on a Windows PC?

• Use only the software resources of the host PC.

• Use all of the hardware on the host PC.

• Use none of the hardware on the host PC.

• Use only the network resources of the host PC.

Which of the following is NOT a benefit of using virtual machines?

• Running incompatible software.

• Isolating different operating systems.

• Increasing physical hardware speed.

• Testing software in different environments.

What is a limitation of using virtual machines?

• They can run any software without restrictions.

• They require no additional resources.

• They may have performance overhead.

• They are faster than running software natively.

Which of the following statements is true about virtual machines?

• They can only run on Apple computers.

• They can emulate any operating system on any hardware.

• They are limited to the capabilities of the host hardware.

• They do not require a host OS.
