Graphical user interfaces and consoles
Computers can display information and let the user give commands to it using two methods: a command line interface (CLI) or a graphical user interface (GUI).
In a command line interface, the user types commands using the keyboard to tell the computer to take an action. For example, the more command available in most operating systems will display the contents of a file.
In many graphical user interfaces, the user can use the computer mouse to click on buttons. For example, one's web browser may have a Print icon to print this page. Some use a touch screen or other method.
Graphical user interfaces are generally thought more easy to use than command lines. Command lines are faster than graphical user interfaces and can be used to give special commands to the computer.
