  • Examples of how we use an operating system in daily use

An operating system acts as the middle man between your hardware and your software. If you are typing on a keyboard for example, which is external hardware, it is your operating system that is making sure the words appear on the screen and then the document, which is software, and is saved to the hard drive, which is hardware again. You will then use your mouse  to search through your document and retrieve any work you wish to edit or re-read.

There are five main operating systems that we use today. The main one is Microsoft Windows but Android, iOS, Linux and Mac OS X are becoming increasingly popular.

Mac OS X is used on Apple computers and is regarded very highly although it can be fiddly for people using it for the first time. Android is used in mobile phones other than the iPhone and Linux is known to be extremely fast and runs the 10 fastest supercomputers in the world.

An operating system lets you have a interface with the computer. Mainly we use things like windows which is a GUI = graphical user interface, this lets us see things with more graphic.

If you use CMD then it lets you see another type of operating system thats not as graphical but does the same thing. But graphical solutions are way more popular
