What makes a computer run?

Software tells the hardware what to do and how to do it. For example, writing and reading programs, and games might be some types of software you have used before.

The operating system is the most important program that runs on your computer. It lets the computer's hardware and software work together.

Using an Internet browser lets you explore the Internet where you can find lots of information, like pictures, videos, and webpages.

Application programs do many different things. For example, Microsoft Word or Google Docs are both word processing programs that let you write book reports, essays, stories, and more.

Antivirus software protects your computer so that it doesn't get a computer virus.

Just like flu viruses get people sick, computer viruses make your computer sick. Viruses can damage information on your computer if you don't have a good antivirus software.
