Wrong.  The *session id* is stored using a cookie if cookies are enabled; otherwise it 
is passed from page to page as part of the URL.  In either case, all the session's 
data are actually stored on the *server*, and the session id is used as a key to them.

Cheers!

Not per se, cookies is one way of using sessions. The other way is to use
the special var SID (without the $ sign, so a constant in a way) like this
(from the manual):

And concerning the reliability, if you store data in a session a user
can't fiddle with the values as easily as when you would save your data
the url.
