There are two types of cookies:
Session (transient) cookies: These cookies are erased when you close your browser, and do not collect information from your computer. They typically store information in the form of a session identification that does not personally identify the user.
Persistent (permanent or stored) cookies: These cookies are stored on your hard drive until they expire (at a set expiration date) or until you delete them. These cookies are used to collect identifying information about the user, such as web surfing behavior or user preferences for a specific site
