Chapter Summary Continued
The TCP and UDP protocols reside at the Transport Layer of the TCP/IP networking model.
UDP is an unreliable and connectionless communications protocol that does not guarantee packet delivery.
TCP is a reliable and connection-oriented protocol that guarantees packet delivery.
TCP uses a three-way handshake in order to establish a communications link between two points.
TCP also uses a sliding window to control the flow of packets and the number of acknowledgements between the two hosts.
TCP and UDP use port numbers from 1 – 65,535 to establish their communications between two points.
