GUI means graphical user interface. This type of operating systems like Windows 98, XP, ME, Vista, 7 and Linux, which allow users to navigate graphic representation of every process or application are classified into this type of operating system.

CUI Operating System
This type of the computer operating systems, where you need to learn the commands for working with that particular operating system . MS DOS is one of the most used operating system. There is a particular command for each process and to bring in variation to the command, you have switches.
