Operating with windows GUI


window is a (usually) rectangular portion of the display on a computer monitor that presents its contents (e.g., the contents of a directory, a text file or an image) seemingly independently of the rest of the screen. Windows are one of the elements that comprise a graphical user interface (GUI).

A GUI is a type of human-computer interface (i.e., a system for people to interact with a computer) that uses windows, icons, pull-down menus and a pointer and that can be manipulated by a mouse (and usually to some extent by a keyboard as well). An icon is a small picture or symbol that represents a program (or command), file, directory (also called a folder) or device (such as a hard disk or floppy disk).

The GUI represents a major advance over the command line interface (CLI) of the console, which displays only text (i.e., no images) and is accessed solely by a keyboard. It has made computers much easier to learn and work with, and it has also led to the development of major new applications for them, including desktop publishing and CAD (computer-aided design).

The words window and windows are generic terms and should not be confused with Microsoft Windows (although they sometimes are). The latter is the trade name that Microsoft selected for its series of operating systems that employ a GUI. (The originally intended name was Interface Manager, but Microsoft’s marketing expert Rowland Hanson convinced co-founder Bill Gates that Microsoft Windows was preferable).
