Cookies are small pieces of data sent from a website and stored on a visitor's browser. They are typically used to keep track of settings you have selected and actions taken on a site. 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 ID 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 expiry date) or until you delete them. These cookies are used to collect identifying information about the user, such as web browsing behavior or user preferences for a specific site.
