Best lightweight Operating System for low-end PC

What is an Operating System?

Operating systems are also software but they act as an interface between computer hardware components and the users. Take an easy example to understand this. 

Let’s assume that you are a boss of a company and there are many workers who are working under you. And the workers are doing different tasks. So that workers are different applications in our case and the bose who is controlling all the tasks from behind like if the worker is doing his job perfectly or not, etc. is operating system in our case. But is there only your company in this world? of course not… There are many different companies with their different names and different works and in our case, those different companies are different operating systems.

Every computer needs an operating system in it. So that it can run other programs. Like, Browsers, Video players, games, etc.
