Character User Interface (CUI)

                  A Character User Interface (CUI) is a way for users to control a computer by typing text-based
                  commands. Because it uses only commands, it’s also called a Command Line Interface (CLI).
                  This type of interface provides a command prompt to the users. In this type of interface, you type
                  commands into a command prompt to make the computer do specific tasks. Examples of CUIs
                  include DOS and the Windows Command Prompt.

                     Prompt by pressing the  Windows + R
                     shortcut key. The Run dialog box appears.

                  Advantages of CUI

                  There are some advantages of using a CUI:
                     It’s simple to understand.

                     It takes input and gives output in text form.
                     It requires less system resources compared to GUIs.                   Tech Tweak

                  Disadvantages of CUI                                               Users can enter commands by
                                                                                     typing one or two lines of text
                  There are also some disadvantages of using a CUI:
                                                                                     called command lines.
                     It’s hard for people to remember all the commands.

                     It’s not user-friendly compared to modern user interfaces.
                     It can be slow because you have to type every command.

                  Graphical User Interface (GUI)

                  A Graphical User Interface
                  (GUI) type of user interface that

                  allows people to interact with
                  computers  using graphical
                  elements like windows,  icons,
                  buttons, and menus. Instead of
                  typing commands like in a CUI,

                  users can click, drag, and drop
                  elements to perform  tasks.
                  This makes it easier because

                  you  don’t  have  to  remember
                  commands. You can control the computer just by clicking with the mouse. Some example of
                  GUIs-based operating systems includes Windows and Mac.
