What is the difference between popups and cookies?

Hi,

A popup is a window that opens on a website. For example, when you browse on "Google" and a advertising window appears right in the middle in front of everything else on the page, or another window for another site pops up.

A cookie is a piece of information related to your browsing that is stored locally on your computer or remotely, to remember usage preferences, a username, a login state to a site, or other information.

For example, when you log into Facebook, close the site, and come back, you’re still logged in... That’s thanks to cookies. But there are also cookies that contain many other types of info (location, browsing preferences, etc., etc., etc.) and can sometimes allow the "tracking" of how a user uses the internet...
