Ad server

An ad server is like a special computer that helps show ads on websites and apps. Let's say you're playing a game on your tablet and suddenly you see an ad for a toy store. That ad probably got there with the help of an ad server.

The ad server will first find out information about you like where you are, what you like or what you've searched for. It uses this information to figure out what kind of ads you might want to see. The ad server then sends the ad to the game or app you're using so you can see it.

The ad server can do this for many different websites and apps. It is like a magical helper that makes sure that the right ads show up for the right person.
