Answer:
The GUI
Explanation:
GUI stands for Graphical User Interface
Behind the scenes, your computer is just working with a lot of 1s and 0s, and that wouldn't be very easy for us to operate.
The GUI means we can interact with our computer in a way that is easy for us to understand as humans. With the GUI every move of the mouse, click, key press (and so on) sends a command to the machine in a language that it understands, and shows us the result on screen in a way that we can understand. :) This cuts out a lot of work and means more people can use the technology we've developed without having to learn complicated commands to use our computers.
