What is an Operating System?

So, what exactly is an OS?
To put it simply, an operating system is an interface that interacts with the hardware. An operating system doesn't have to be real fancy, it just has to work. The most common examples of operating systems are iOS (or Android) and Windows. iOS (iPhone Operating System) is the most used operating system on phones, next to Android. It's file system, or the "thing" that stores files on the hard-drive, is not accessible, but it doesn't need to be. Windows is the most commonly used operating system of all time (Mostly because Microsoft had a monopoly on OSs in the 90's (Thank's Bill!)). It's file system is accessible, everybody knows that (File Explorer). Other OS's include Mac OS X, Linux, and the sea of open source OSs on GitHub.

Why care about building an OS?
It may seem like this is a time waster, or a clock watcher, if you will (I have a word-a-day calendar), but by making your operating system, you just contributed to the never-ending field of technology. And that feeling that you get when click the Create Project button is extraordinary. Operating Systems are everywhere, and it can feel amazing to create one! So let's get started and contribute to technology.
