Cookie is basically a global array accessed across web browsers. Many a times used to send/receive values. it acts as a storage mechanism to access values between forms. Cookies can be disabled by the browser which adds a constraint to their use in comparison to session.

Session can be defined as something between logging in and logging out. the time between the user logging in and logging out is a session. Session stores values only for the session time i.e before logging out. Sessions are used to track the activities of the user, once he logs on.
