Slower (because of retransmission) stateful once connection is lost its lost, cannot resume it. TCP Example (Code) telnet 127.0.0.1 8080 Explain UDP Pros Statless, Less bandwidth smaller packets Faster to transmit Cons no ack, no garenteed delivery, no congestion control no ordered packets UDP client echo "foo" | nc -w1 -u 127.0.0.1 41234 2:24 osi model tag 14:20 stateful.
