Linux is an operating system, just like Windows or Apple. It was created by Linus Torvalds in 1991. Since then it has become the predominate operating system for servers running businesses, government agencies and a majority of web sites. Most of the public doesn’t know this, but because its free and doesn’t have the marketing budget of a Microsoft or Apple most people still don’t know about Linux. It’s now easy to install and use. And by the way, Linux is safer and more secure than Microsoft or Apple!
