There is no two way communication, no virtual circuit, no sequencing, no reliability). It is quite quick and requires much less CPU overhead, but lacks some of the advantages of TCP or Transmission Control Protocol - a host to host protocol used for downloading files. (TCP has error checking, sequencing, acknowledgments, and is very reliable. It is comparable to a phone call where you might say "Are you there?" "Yes I'm here." " I am ready to send you some information" "I am ready to receive it" "Did you get the information I just sent?" etc. etc. etc.) Before jumping to the conclusion that a hyperlink is bad, or that a server on the WWW is down, you need to try a hyperlink at least several times due to the inherent unreliability of the UDP protocol.
