Every Wednesday we are going to put up a new Computer term that everyone might not understand, this is our first Wednesday so here it goes!
HTTP cookies are used by Web servers to differentiate users and to maintain data related to the user during navigation, possibly across multiple visits. HTTP cookies were introduced to provide a way to implement a "shopping cart" (or "shopping basket"), a virtual device into which the user can "place" items to purchase, so that users can navigate a site where items are shown, adding or removing items from the shopping basket at any time.
