“An operating system is software, consisting of programs and data, that runs on computers, manages computer hardware resources, and provides common services for execution of various application software. The operating system is the most important type of system software in a computer system. Without an operating system, a user cannot run an application program on their computer, unless the application program is self booting.”
Now that Wikipedia answered the question what is an operating system I would like to explain why I am interested in the next step. The human factor. The social operating system. SOS.
