Software is all around you:
Computer coding is used for many different things.
Software is all around you, even in devices that you might not think would need it. Of course, you expect to find and use software on a personal computer, but software also plays a role in running airplanes, cars, cell phones, and even toasters. On a personal computer, you use word processors to write documents, Web browsers to explore the Internet, and e-mail programs to send messages. These programs are all examples of software. Software developers create software with the help of powerful tools called programming languages.
