Computer Basics: Understanding Operating Systems

Did you know that you and your computer speak different languages? It doesn’t speak Spanish,or Swedish, or Chinese; it speaks in ones and zeroes.  You can’t communicate directly with your computer; that’s where your operating system comes in.  The operating system is the program that lets you interact with your computer.  Together, the operating system and computer hardware form a complete system that determines what your computer can do.  There are many different operating systems.  Two of the most common ones are Microsoft Windows and Mac OS X.  Windows comes reloaded on most personal computers; Mac OS X runs on all new Macs.  Operating Systems aren’t just for computers and laptops, though.  Mobile devices run mobile operating systems like Apple iOS or Google Android.  Operating systems for mobile devices are designed for interactions with smaller touch-screens.  Before downloading new software, or applications, to your computer or mobile device, you should check to see if the application is compatible with your operating system.  Some applications work on all operating systems, but others only work on certain ones.  So, get to know your operating system to see how it works and what it can do.
