There are so many different computers with so many different operating systems. Apple invented the home computer, my first computer was a Commodore 64, I've used DOS and Windows for most of my life, there's Mac OS and Linux, and you can do anything on the World Wide Web.
|Windows. Microsoft Windows is an operating system for personal computers. Windows has a graphical user interface, so instead of typing everything on a keyboard like in DOS, you can use menus and the mouse to do things like running programs.|
This completes computers.
