What is a cookie?
A cookie is a small text file that is placed and stored on your computer/device to provide you with internet access.
It is possible that cookies are required to ensure the proper functioning of a web site, as websites are stateless (they do not retain user information from one internal page to another). They are also sometimes used for tracking user actions within one website or across multiple websites in order to gather information about their behaviour and interests in order to offer relevant advertisements.
Cookies that are necessary
In general, necessary cookies are not used for tracking purposes and are not shared between web sites. Users are commonly authenticated using cookies when performing a necessary action. Whenever you log in to a web site,a cookie is stored in your browser, which contains some information that the web site uses to remember your identity when you visit another internal page or refresh the page.
Additionally, cookies are used so that a web server can keep track of what items you have added to your shopping cart, load balancing information, and so forth.
Cookies that store preferences
A preference cookie is used to allow a web site to remember information that is used to customize how the website appears and behaves for each individual user. This may include storing a selected currency, region, language or theme.
Cookies for analytical purposes
Although analytical cookies are not necessary, they are used to gather useful information on how web sites are used, identify issues, and identify what needs to be improved on the site and what content is most useful. There are some analytics services that collect information that can be used to identify the user, though most of the information is anonymous.
