![]() Cursors are also named pointers in GUI systems. On screen cursor follows the instructions from hardware in almost real-time. Icon displays application and programs installed on a system in the form of small pictures.Ĭursor - Interacting devices such as mouse, touch pad, digital pen are represented in GUI as cursors. When these icons are clicked or double clicked, the application window is opened. Icon - An icon is small picture representing an associated application. The menu can be programmed to appear or hide on mouse clicks. Menu - Menu is an array of standard commands, grouped together and placed at a visible place (usually top) inside the application window. All modern web-browsers use this feature. This interface also helps in viewing preference panel in application. Tabbed Document Interface has come up to open multiple documents in the same window. Tabs - If an application allows executing multiple instances of itself, they appear on the screen as separate windows. A window may contain another window of the same application, called child window. They can be moved anywhere on the screen. Windows can be minimized, resized or maximized to the size of screen. It is easier for a user to navigate in the file system in an exploring window. Contents in a window can be displayed in the form of icons or lists, if the window represents file structure. Window - An area where contents of application are displayed. A GUI system has following elements such as: GUI provides a set of components to interact with software or hardware.Įvery graphical component provides a way to work with the system. With advancing technology, the programmers and designers create complex GUI designs that work with more efficiency, accuracy and speed. Typically, GUI is more resource consuming than that of CLI. ![]() GUI can be combination of both hardware and software. Graphical User Interface provides the user graphical means to interact with the system. When output is produced, command prompt is displayed on the next line. Output on command execution is shown inline on the screen. It moves as the user writes or deletes something.Ĭommand - A command is an executable instruction. Cursor is mostly found in blinking state. It is generated by the software system.Ĭursor - It is a small horizontal line or a vertical bar of the height of line, to represent position of character while typing. CLI ElementsĪ text-based command line interface can have the following elements:Ĭommand Prompt - It is text-based notifier that is mostly shows the context in which the user is working. There are methods like macros, scripts that make it easy for the user to operate.ĬLI uses less amount of computer resource as compared to GUI. ![]() Earlier CLI were not programmed to handle the user errors effectively.Ī command is a text-based reference to set of instructions, which are expected to be executed by the system. The user needs to remember the syntax of command and its use. CLI is minimum interface a software can provide to its users.ĬLI provides a command prompt, the place where the user types the command and feeds to the system. CLI is first choice of many technical users and programmers. UI is broadly divided into two categories:ĬLI has been a great tool of interaction with computers until the video display monitors came into existence. ![]() The software becomes more popular if its user interface is: UI can be hardware or software or a combination of both. UI can be graphical, text-based, audio-video based, depending upon the underlying hardware and software combination. UI provides fundamental platform for human-computer interaction. User interface is part of software and is designed such a way that it is expected to provide the user insight of the software. Today, user interface is found at almost every place where digital technology exists, right from computers, mobile phones, cars, music players, airplanes, ships etc. User can manipulate and control the software as well as hardware by means of user interface. User interface is the front-end application view to which user interacts in order to use the software.
