The graphical user interface (GUI), is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation.

GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.

In computing, a plug-in (or plugin, add-in, addin, add-on, addon, or extension) is a software component that adds a specific feature to an existing computer program.

When a program supports plug-ins, it enables customization.

The common examples are the plug-ins used in web browsers to add new features such as search-engines, virus scanners, or the ability to use a new file type such as a new video format.

Well-known browser plug-ins include the Adobe Flash Player, the QuickTime Player, and the Java plug-in, which can launch a user-activated Java applet on a web page to its execution on a local Java virtual machine.

An Internet chess server (ICS) is an external server that provides the facility to play, discuss, and view the board game of chess over the Internet.

The term specifically refers to facilities for connecting players through a variety of graphical chess clients located on each user's computer.

A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically.

The ability of computers to follow a sequence of operations, called a program, make computers very applicable to a wide range of tasks.

Such computers are used as control systems for a very wide variety of industrial and consumer devices.

This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones.

The Internet is run on computers and it connects millions of other computers.
