What is a client and server?

Client:

Your phone, computer, or tablet is the client. It's the one that asks for things, like websites, videos, or emails. When you type a web address or click a link, your device becomes the client, sending a request to the server.

Server:

The server is like a helpful friend who gives you what you asked for. It's a big computer that stores websites, files, and other stuff. When the server gets a request from a client, it sends back the information needed. It's like asking a friend for a book, and they hand it to you.
