Operating System

An operating system (OS) is the software that allows a user to run other applications on a computing device. It is the base infrastructure software component of a computerized system. It oversees and controls all major operations of the computer.

The most widespread computer operating systems are Windows from Microsoft and MacOS from Apples and Linux.

And the most popular operating system for mobile phones include Apple’s iOS and Google’s Android. We also have the RIM’s BlackBerry OS and Microsoft’s Windows Mobile.

 

The operating system manages a device’s hardware resources, including:

  • Network devices such as modems, routers and network connections
  • Storage devices such as internal and external drives
  • Input devices such as a keyboard and mouse
  • Output devices such as display monitors, printers and scanners

For large devices, the operating system has even greater responsibilities and powers. It is like a traffic warden — making sure that various programs and users running at the same time do not interfere with each other. The operating system secures a computer device or phone, making sure that unauthorized personnel or users do not access the system.
