What are Cookies?
Cookies are small files, consisting of letters and numbers, which will be stored on the computer, mobile terminal or other equipment of a user who accesses the Internet. Cookies are installed by the request issued by a web server to a browser (eg Internet Explorer, Chrome) and are completely “passive” (do not contain software, viruses or spyware and can not access the information on the user’s hard driver) .
What are cookies used for?
Cookies can provide a faster and easier interaction between users and websites. For example, when authenticating a user on a particular website, the authentication data is stored in a cookie; subsequently, the user can access that site without having to log in again.
In other cases, cookies may be used to store information about the activities carried out by the user on a particular web page, so that he can easily resume those activities at a later access to the site. Cookies tell the server what pages to show the user so that they do not have to remember this or navigate the entire site from the beginning. Thus, cookies can be assimilated to “bookmarks” that tell the user exactly where he stayed on a website.
Similarly, cookies can store information about products ordered by the user on an e-commerce site, thus making possible the concept of “shopping cart”.
