Different user interface elements:

User interface is part of software and is designed such a way that it is expected to provide the user insight of the software. UI provides fundamental platform for human-computer interaction.

The software becomes more popular if its user interface is:

  • Attractive
  • Simple to use
  • Responsive in short time
  • Clear to understand
  • Consistent on all interfacing screens

UI is broadly divided into two categories:

  • Command Line Interface
  • Graphical User Interface

Command Line Interface (CLI)

CLI has been a great tool of interaction with computers until the video display monitors came into existence. CLI provides a command prompt, the place where the user types the command and feeds to the system. The user needs to remember the syntax of command and its use. CLI uses less amount of computer resource as compared to GUI. A text-based command line interface can have the following elements:

  • Command Prompt - It is text-based notifier that is mostly shows the context in which the user is working.
  • Cursor - It is a small horizontal line or a vertical bar of the height of line, to represent position of character while typing.
  • Command - A command is an executable instruction. It may have one or more parameters.

Graphical User Interface

Graphical User Interface provides the user graphical means to interact with the system. GUI can be combination of both hardware and software. Using GUI, user interprets the software.GUI provides a set of components to interact with software or hardware. Every graphical component provides a way to work with the system. A GUI system has following elements such as:

  • Application Window - Most application windows uses the constructs supplied by operating systems but many use their own customer created windows to contain the contents of application.
  • Dialogue Box - It is a child window that contains message for the user and request for some action to be taken.
