Cookies are small text files that are stored on your computer while you browse a website or use a web application.
Such files contain various types of information designed to enrich the functionality of a website (such as for online purchases or customizing messages in accordance with one's preferences), to collect statistical data and, in general, to improve the user browsing experience.
There are various types of cookies, which have been classified in accordance with their characteristics and methods of use, as per the following:
Session cookies / Permanent cookies
Session cookies
are stored temporarily on your computer while you browse a site (e.g. to keep track of the chosen language). Session cookies are only stored for a short period and are deleted when the browser is closed.
Permanent cookies are, by contrast, stored on your computer for a long period of time, in accordance with the expiry date set when the cookie is created. Such cookies allow websites to store information for future visits to the site by a user, perhaps to avoid making the user enter his or her access details each time.
First-party cookies / Third-party cookies
First-party cookies are created by the websites themselves (the same domain as the one indicated in the browser's address bar) and can only be read by those websites.
Third-party cookies are, by contrast, created by domains other than those indicated in the browser's address bar, that is, by organisations that are not the owners' of the website. Such cookies can be used, for example, to collect information for advertising purposes, to customize content and to track visits to the site.
