Answer:
GUI provides simple and easy way to operate computers.
Explanation:
Before GUI there were only CUI (Character User Interface) where the user needs to remember lots of commands to interact with computer and it is also time consuming.
Eg. DOS (Disk Based Operating System).
This problem was overcome by GUI where it contains buttons where the user can use the mouse to click, double click or right click according to the options provided by the environment. GUI is the successor of CUI.
