Operating System Functions 1: User Interface
This is the first of six short computer science lessons about the functions of an operating system. In this lesson you will learn about user interfaces. The lesson compares graphical user interfaces, GUIs, and command line interfaces, CLIs. It also mentions some more modern user interfaces such as artificial intelligence (AI) enabled voice control, gestural control and brain computer interfaces.
