What is a cookie?
A cookie is a harmless text file stored in your browser when you visit almost any web page. The usefulness of the cookie is that the web can remember your visit when you return to browse that page. Although many people do not know it, cookies have been used for 20 years, when the first browsers for the World Wide Web appeared.
What is NOT a cookie?
It is not a virus, not a Trojan, not a worm, not spam, not spyware, nor does it open pop-up windows.
What information does a cookie store?
The cookies do not often store sensitive information about you, such as credit card or bank account information, photographs, ID or personal information, etc. The data they keep are technical, personal preferences, personalization of content, etc.
The web server does not associate you as a person but with your web browser. If you regularly browse with Internet Explorer and try to browse the same web with Firefox or Chrome, you will see that the web does not realize that you are the same person because it is associating the browser, not the person.

- Advertising cookies: They show advertising based on your browsing, country of origin, language, etc.
