Each node or device that will communicate directly onto the
network requires an IP address, including HP Jetdirect-
connected devices.
Transmission Control Protocol (TCP)
TCP handles breaking the data into packets and recombining
the packets on the receiving end by providing a connection-
oriented, reliable, and guaranteed delivery service to another
node on the network. When data packets are received at their
destination, TCP calculates\x1a checksum for each packet to
verify the data is not corrupt. If the data in the packet has been
corrupted during transmission, TCP discards the packet and
requests that the packet be resent.
User Datagram Protocol (UDP)
UDP provides similar services to TCP. However, UDP does not
acknowledge data receipt and supports request/reply
transactions with no added reliability or guarantee of delivery.
UDP is used when acknowledgment and reliability are not
required, such as during a "discovery broadcast."
