What is an Operating System?
A model displays Japanese mobile phone operator Willcom's smart phone, 'D4', which comes equipped with the Windows Vista operating system.
For other devices, an operating system creates the ability to:
- serve a variety of purposes
- interact with users in more complicated ways
- keep up with needs that change over time
In any device that has an operating system, there's usually a way to make changes to how the device works. This is far from a happy accident; one of the reasons operating systems are made out of portable code rather than permanent physical circuits is so that they can be changed or modified without having to scrap the whole device.
For a desktop computer user, this means you can add a new security update, system patch, new application or even an entirely new operating system rather than junk your computer and start again with a new one when you need to make a change. As long as you understand how an operating system works and how to get at it, in many cases you can change some of the ways it behaves. The same thing goes for your phone, too.
Regardless of what device an operating system runs, what exactly can it do?
