Timeline of operating systems

A timeline of operating systems is a way to chart the different versions of software designed to help computers work. Operating systems make it easier for people to use their computers and other devices. When you turn on a computer, the operating system is the software that helps it decide what to do and how to do it.

Every now and then, new updates become available for operating systems that give us better, faster and more secure ways of using our computers. The timeline of operating systems tracks these updates from oldest to newest, like a timeline of events.
