To Sum Up

                           A computer system is a combination of hardware and software.

                          Software is a program or collection of programs that performs a task.
                          An operating system is a system software that works as a mediator between the user
                         and the computer hardware.
                          In CUI operating system, the user sends commands and instructions to the computer
                         in character form i.e., by typing commands at the command prompt.

                          In GUI operating system, the interface is graphical i.e., the user interacts with figures
                         and graphs on the screen.
