ELI5: Explain Like I'm 5

Cookies

Cookies are like little notes that your computer writes down and keeps track of when you go on websites. They help remember things like your username, your preferences, or things you've added to your shopping cart. It's like a special code that helps the website remember you even if you leave and come back later. And just like how you might give your teacher a note to remind them of something, cookies help remind websites of things you've done before.
