what is needed for data communication?
536513
These technologies include telecommunications, computer networking and radio/satellite communication. Data communication usually requires existence of a transportation or communication medium between the nodes wanting to communicate with each other, such as copper wire, fiber optic cables or wireless signals.

TCP and UDP are the most commonly used connection protocols for data travel on the Internet. Learn why UDP is ideal for VoIP. In VoIP, audio samples are placed into data packets for transmission over the IP network. ... TCP is so prevalent on the Internet that it's typically combined with IP and written as TCP/IP.

The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. ... They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.
