Command Line Interface:-

Command-line interfaces are the oldest of the interfaces. This type of user interface allows the user to interact directly with the computer by typing commands. Typing commands is not that easy because you just can’t type anything, you have to type very specific words so that the computer is able to understand. This operating system is used in the rear case. because modern time user needs a GUI based interface. At this time many types of user interface available in the market.
1.   You can only type text to give commands to the computer as in MS dos.
2.   There are no images and graphics on the screen.
3.   There was no need for a mouse as CLI did not support the use of pointing devices.
4.   In CLI only one task can run at a time.
5.   It is also known as a single user interface.
6.   Example: DOS and Unix

Advantages of using a command-line interface are:

  ·        It is faster than the other types of user interfaces.
  ·         Fast data transfer in CLI.
  ·         Memory (RAM) is used lesser than GUI.
  ·         It is cheaper to use as a lesser resolution screen can be used.
  ·         Lesser CPU processing time is needed.
  ·         It does not need Windows to run.

Disadvantages of using a command-line interface are:

  ·         Without the known commands, you cannot work on the CLI
  ·         A lot of commands have to be learned to use this interface.
  ·         One needs to be very specific and careful when typing the commands. Even a single spelling mistake may lead to instruction failure.
  ·         There are no images and graphics on the screen.

Graphical user interfaces (GUI)

A GUI (Graphic User Interface) is a graphical representation in which the users can interact with software or devices through graphical icons. GUI is the most common type of user interface in use today.
  ·         In GUI more than one task can run simultaneously
  ·         It is a very user-friendly interface
  ·         Most modern computer use GUI
  ·         This is an interface that makes use of graphics, images, and icons etc.

Advantages of a graphic user interface are:

  ·         This type of user interface is easy to use.
  ·         It is easy to explore and find your way around the system using a GUI interface
  ·         You do not have to learn complicated commands.
  ·         It is based on a graphical representation
  ·         Users do not need to know any programming languages.
  ·         It is also known as a multi-user operating system.

Disadvantages of a graphic user interface are:

  ·         GUIs take up a much larger amount of hard disk space than other interfaces.
  ·         They use more processing power than other types of interface.
  ·         They need significantly more memory (RAM) to run than other interface types.
 ·      They let you exchange data between different software applications
