Cookies are small files that are delivered and installed on a visitor's browser for the purpose of tracking the visitor's activities on that particular site.

These cookies are stored in temporary memory and remain valid only while the web browser is open. Once the browser is closed, these cookies are deleted. The second type is the persistent cookie. These cookies remain embedded within the browser for a predetermined period of time during which the cookies send back specific information to the website server about the viewer's activity.
