What Is Gui


History And Features Of Cli

GUI is graphically based, being advanced and more user friendly than the text-based Command Line Interface. The graphical software mantenimiento interface was introduced by Douglas Engelbart, Alan Kay in 1981 along with a number of more researchers.

  • Many mobile devices can now be controlled by spoken commands as well.
  • Therefore, mobile operating systems are designed to use a touchscreen interface.
  • CLI is the acronym used for Command Line Interface, which are conventional interfaces extensively used in 1980’s.
  • While these types of input devices are sufficient for desktop computers, they do not work as well for mobile devices, such as smartphones and tablets.
  • For several decades, GUIs were controlled exclusively by a mouse and a keyboard.
  • A command-line interface allows users to write commands in a terminal or console window to communicate with an operating system.

GUI requires more memory as it contains a lot of graphical components. CLI is a command interface, and it does not require more memory. The zooming user interface is a related technology that promises to deliver the representation benefits of 3D environments without their usability drawbacks of orientation problems and hidden objects. It is a logical advance on the GUI, blending some three-dimensional movement with two-dimensional or 2.5D vector objects. In 2006, Hillcrest Labs introduced the first zooming user interface for television.

GUIs can be made quite hard when dialogs are buried deep in a system or moved about to different places during redesigns. Also, icons and dialog boxes are usually harder for users to script.

After typing a command, the result users got would be either text information or specific action performed by the computer. GUI can easily connect and create a network with other computers to software transportes gain access. In the case of CLI, the user needs to get permission to access other devices. Unlike CLI, Graphical user interface need not be memorized and so is easy to learn and execute.

What is an interface for?

But, the operating system may not give you all the menus and buttons to perform all tasks. This leaves you overwhelmed if you have to do repetitive tasks. For example, when you have to handle hundreds of files within a folder, CLI enables you to use a single command to do automate the repetition easily.

Successively, Apple came up with LISA, a GUI supporting computer on 19th January 1983. Most popular examples of Command-Line interface are MS-DOS and Unix based operating systems. Although many CLI offers multiple windows view, GUI generally has a higher ability to operate multiple tasks at the same time with ease. A GUI does not have the same level of functionality and granular control as a command line interface. It can be used to easily do things that are difficult or even impossible to do with a GUI.
