Imagine that your computer is a big castle and the things you do on it, like play games or type on a word document, are the king and queen who live in the castle. The king and queen (your programs) need to talk to the people who make the castle work (the computer's hardware) so they can play their games or write their documents. But they can't talk to the people who make the castle work directly, so they talk to the castle's boss (the kernel) instead. The boss (kernel) is the one who makes sure that the king and queen (programs) have enough room to play and write, and that the people who make the castle work (hardware) are doing their jobs right. Think of the kernel like a conductor in an orchestra that makes sure all the instruments are playing in harmony together.
