An operating system is the most important software that runs on a computer. It manages the computer's memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's language. Without an operating system, a computer is useless.
Your computer's operating system (OS) manages all of the software and hardware on the computer. Most of the time, there are several different computer programs running at the same time, and they all need to access your computer's central processing unit (CPU), memory, and storage. The operating system coordinates all of this to make sure each program gets what it needs.
Operating systems usually come preloaded on any computer you buy. Most people use the operating system that comes with their computer, but it's possible to upgrade or even change operating systems. The three most common operating systems for personal computers are Microsoft Windows, Mac OS X, and Linux.
Modern operating systems use a graphical user interface, or GUI (pronounced gooey). A GUI lets you use your mouse to click icons, buttons, and menus, and everything is clearly displayed on the screen using a combination of graphics and text.
Each operating system's GUI has a different look and feel, so if you switch to a different operating system it may seem unfamiliar at first. However, modern operating systems are designed to be easy to use, and most of the basic principles are the same.

Computer Science Engineer
I love to see students succeed in their careers!
After working as a Researcher and Developer for over 4 years in my bachelor's time, I decided to work full-time as a private software trainer. I have 3 provisional patents in technologies around WiFi, Operating Systems and Real Time Communication for Speech Impaired People. My research papers have been appreciated and have won awards across various university level competitions. From amateur to professional by turning your doubts into clear facts.
Your Knowledge into Industrial Level skills!
Sorry to tell you because what I expect is that this course shows a video about what is hardware, software, and other parts of the operating system. To clarify it specifically like in a picture or video wherein an individual operates a computer. And what I see is just like reporting in a class.
More skills acquisition
Not at all, the instructor keeps repeating the context over and over and over, most of the sections can be condensed to a 3rd of the time if the points are streamlined and simplified without rewording and repeating the same information.
