Session cookies are temporary cookie files, which are erased when you close your browser. The next time you visit that site it will not recognise you and will treat you as a completely new visitor as there is nothing in your browser to let the site know that you have visited before.

These remain on your hard drive until you erase them or they expire. How long a cookie remains on your browser depends on how long the visited website has programmed the cookie to last. (www.allaboutcookies.org)
