Imagine a very smart parrot that has read almost the entire library of the internet. Stories. Textbooks. Recipes. News. Conversations. That parrot is an LLM.

A graphics card is a helper inside your computer that is really good at drawing pictures very fast. Its main job is to turn numbers into images that you see on your screen. Games, videos, and even moving windows all rely on it.

RAM is like a desk in your brain for a computer.

Imagine you are doing homework. You spread your books, papers, and pencils on your desk. Everything you need right now is right there. You can grab it fast. That desk is like RAM. 

Imagine you want to send a toy to a friend. You could put the toy in a box with everything it needs to survive the trip. You add padding. You add instructions. You make sure the box works no matter what truck carries it. A Docker container is like that box, but for software.

Imagine you and your friends are building something together, like a big Lego castle. You all want to help, but if everyone grabs pieces at the same time, things can get messy. Pieces get lost. Someone breaks a wall. Nobody remembers how it looked yesterday. GitHub is like a smart playroom that keeps the Lego castle safe while everyone works on it.
