Originally, it was just a graphical user interface on top of MS-DOS – a state of affairs that lasted until the release of Windows 95, when MS-DOS products were integrated into Windows. Windows 95 was a huge departure from the previous systems and was the first major step in Window’s transition from GUI to operating system. Windows registry is a master database which is used to store all settings on your computer Windows interface was not interchangeable until Windows 8.  A terminal or command prompt is a black box ideally used to execute commands. It is also called the Windows Command Processor. Windows follows a directory structure to store the different kinds of files of the user.	This operating system from Apple stands older than Windows. It was first released in 1984. It began as a graphical user interface right from its inception. In 2005 the design and structure of MAC OS were changed to Intel x86 based architecture. MAC stores all application settings in a series of .list files which have the various preferences folder in MAC MAC has a facility to bridge virtual network interfaces.  MAC provides a console as a terminal application. It has a console, command line, prompt and terminal. Command line is used to type your commands.  The file structure of MAC is commonly known as MAC OS X. If you go to dig into your MAC’s hard disk through finder you will see many directories.	It was initially developed in Finnish University. It was released in 1991 and designed for GNU developers. GNU developers later integrated it into Linux. It is open to consumers and everyone can use as per their specifications. Linux also does not have a specific registry of its own. Linux is easy to switch interfaces. You can switch the environment without having to carry all installations. Linux also provides a terminal. You can find terminal at: Applications -> System or Applications -> Utilities. In addition to this, there is also a shell prompt. Linux has a completely different file structure form Windows and MAC. It was developed with a different code base. It stores data in the form of a tree.
