In America a biscuit is served with food such as lunch and dinner its a type of bread and a cookie is dessert sweet and a tasty treat.
They seems very similar but I can't find biscuits w/ raisins so I prefer cookies w/ raisins or cookies w/ chocolate chips
Thats the difference between Biscuit and Cookies. But there are another cookies present. Whenever I logout from forum then they shows that all cookies has been deleted. What is that cookie supposed to mean?
It means that the invisible forum troll has stolen your cookies and ate them all.. But in all seriousness, they are HTTP cookies, used in storing your user data on your computer.. More info here: http://en.wikipedia.org/wiki/HTTP_cookie
