What is your OS? I know your OS [click me]

An operating system (sometimes abbreviated as "OS") is the program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer. The other programs are called applications or application programs. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition,users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI).

Examples of popular modern operating systems include Android, BlackBerry 10, BSD, Chrome OS, iOS, Linux, OS X, QNX, Microsoft Windows,[3] Windows Phone, and z/OS.

OS X

Information about:

A history of OS X / Apple

OS X is the newest of Apple Inc.'s Mac OS line of operating systems. Although, under its original name of Mac OS X, it was officially designated as simply "version 10" of the Mac OS, "version 9" had a completely differentcodebase as well as dramatic changes in user interface. Mac OS had been Apple's primary operating system since 1984, and the family was backward compatible, so OS X could virtualize Mac OS 9 until version 10.5.

OS X formerly known as Mac OS X, is a series of Unix-based graphical interface operating systems developed and marketed by Apple Inc. It is designed to run on Mac computers, having been pre-installed on all Macs since 2002. It was the successor to Mac OS 9, released in 1999, the final release of the "classic" Mac OS, which had been Apple's primary operating system since 1984.

Mac OS is a series of graphical user interface-based operating systems developed by Apple Inc. for their Macintosh line of computer systems.

The original operating system was first introduced in 1984 as being integral to the original Macintosh, and referred to as the "System". Referred to by its major revision starting with "System 6 and "System 7", Apple rebranded version 7.6 as "Mac OS" as part of their Macintosh clone program in 1996. The Macintosh, specifically its system software, is credited with having popularized the early graphical user interface concept.
