1.1.3 Inputs Outputs and Storage - Virtual Machines Quiz

What is a virtual machine (VM) commonly compared to?

• A physical computer within another computer

• A software program that improves computer performance

• A hardware component that enhances storage capacity

• A network server providing additional resources

Which types of code can virtual machines run?

• Only native machine code

• Only high-level programming languages

• Special kinds of code, like Java programs

• Only assembly language

What is one of the benefits of using virtual machines?

• They increase the speed of the main computer

• They eliminate the need for an operating system

• They help use the main computer's resources more efficiently

• They provide additional physical hardware

What is a drawback of virtual machines?

• They cannot run multiple instances on one computer

• They are always faster than running programs directly on the computer

• They can be more complicated to manage

• They do not allow for changes and management of the virtual environment

What does it mean when it is said that virtual machines "keep things separate"?

• They store data in separate physical locations

• They create little worlds inside your computer that are isolated from each other

• They separate the user interface from the operating system

• They separate the internet from the local network

What is one of the benefits of using virtual machines according to the text?

• They require more energy to run multiple applications.

• They allow old software to run on new computers by creating a special space.

• They prevent students from learning about computers.

• They cannot test software before it is released.

How do virtual machines help in keeping things safe and separate?

• By using a lot of physical computers.

• By allowing one room's problems to affect the others.

• By acting like rooms with high walls, preventing issues in one from affecting others.

• By consuming more resources to maintain separation.

What analogy is used in the text to describe the concept of virtual machines?

• A sandbox where you can test different toys.

• A playground for learning.

• A big computer that acts like many smaller ones.

• A room with high walls.

Why might software developers use virtual machines?

• To increase the risk of breaking their main computer setup.

• To ensure software works only on one type of computer.

• To test software on different setups without needing many physical computers.

• To use more energy and resources.

What is the purpose of using virtual machines in schools, as mentioned in the text?

• To prevent students from accessing computers.

• To let students play with different computer setups without breaking anything.

• To make it harder for teachers to manage the classroom.

• To use more physical computers for learning.
