Question 2

Give a use and an advantage of your two interfaces

Answer 2

With a GUI, the end-user points and clicks on icons, buttons and menus using their mouse, touch screen, keyboard or other device.
A GUI is the most common interface for software applications, mobile apps, and operating systems. It is designed to be very intuitive to use, without needing much text.

Question 3

Advantage of a GUI

Answer 3

A GUI makes the operation of the computer as friendly as possible by using high resolution graphics and pointers. Instead of typing in commands you enter them by pointing and clicking.
It should be intuitive and fun to use without additional instructions. There is no need to know programme commands. It is easier to customise an application or environment using a GUI.
