What are cookies?

Cookies are tiny text files recorded by your browser onto your computer for the websites you are visiting. They act as a memory, where sites can store information about your visit in order to use it when you open the next page. Every site can only set or read their own cookies, and only when your browser allows it. Usually, browsers are set by default to allow cookies.
