An operating system is required in order to run programs and use a computer. It also manages hardware and executes functions in order to make sure that the programs run properly. Any device that runs programs must have some type of operating system, including video game consoles and even some smaller electronics, such as watches and GPS devices. There are several types of operating systems that are widely used, including Microsoft Windows, Linux, and Mac OS X. Windows is the operating system for personal computers, serving roughly 90% of computer users. The most popular versions of Windows are XP and Windows 7, both of which can be purchased for home or business use. Windows 7 has also become more popular with the use of touch screen monitors, allowing for a more interactive computer experience.
Linux is open-source software, which allows for more customization and is generally used by more advanced computer users. It is also often run on mobile phones and other large servers, but only about 2% of computers are equipped with the software. Mac OS X comes installed on Apple computers, and is very popular among those who prefer Macs over PCs. The operating system can be difficult to adapt to initially, but often those who switch enjoy the benefits of using this software. It is also very customizable for each individual user, and is most preferred by individuals who utilize media resources, since Mac OS X is well known for its compatibility with web design, visual arts, and other similar software. Users generally will find an operating system that they feel is the easiest to use, and will try to stick with that specific type of software for all of their electronic devices in order to maintain continuity throughout any technological advancements.
