A cookie is like a special type of secret note that a website gives to your computer when you visit it. The note is a tiny text message that is stored on your computer so that when you go back to the same website later, it will remember who you are and what you did before.

This cookie can remember things like your username, password and what pages you visited on that website. It's like a little helper that makes your browsing experience better because you don't have to sign in or type information again and again.

However, cookies can also track your personal information and be used to show you targeted ads or gather data about your behavior online. That's why it's important to be careful and only allow cookies from websites that you trust.
