I'm sure that more than once when you enter a website you've heard the famous "accept cookies" message, but what exactly are they and what are they for?
Cookies are part of the measurement methods of websites, they are data fragments that are accumulated in a text file on the computers' hard drive.

They are generated by web servers, whose mission is to send cookies to different browsers. Once installed, the browsers return the information collected about user behaviour to the servers, making the user see one information or another in their browser.
