What are cookies?
Cookies are small text files used by websites to store user information, such as login information, site preferences or activity, so that the website displays information relative to the user.
For example, when a user logs into a site, that user's details are kept in a cookie file created by their web browser. This file tells the site that the user is logged in.
If cookies were not used, a user would have to login every time the page was refreshed or a new page was loaded. Thus, cookies are an essential part of modern websites, as they allow the website to be tailored to the individual user.
