Abstract

An operating system allows application programs to access the hardware of computer. A user interface allows a user to access application programs in an easy-to-use way. In a text-based system the user enters text commands which are then interpreted by the operating system. Typical commands are to run application programs, copy files and so on. With a graphical interface, applications programs are represented by graphical objects (icons) and options are selected using menus. Rather than entering commands from the keyboard a mouse pointer is normally used to select objects. This usage of Windows, Icons, Menus and Pointers (WIMPs) is typically known as a Graphical User Interface (GUI).
