Ben le UDP, c'est protocole de transmisson en mode non-connecté alors que le TCP est en mode connecté. C'est écrit là:
Citation :
UDP and TCP are network protocols. A protocol is a known format for
transmitting data between two hosts. It determines such things as the
type of error checking, the data compression method, how the sending
device indicates that it has finished sending a message, and how the
receiving device indicates that it has received a message.
Both UDP (User Datagram Protocol) and TCP (Transmission Control
Protocol) are transport layer protocols that run over IP networks.
UDP is a connectionless protocol. This means it does not perform
retransmission of data and therefore provides very few error recovery
services. UDP instead offers a direct way to send and receive
datagrams (packets) over the network; it is used primarily for broadcasting messages.
TCP, on the other hand, provides a connection-based, reliable data
stream. (Whereas the IP protocol deals only with packets, TCP
enables two hosts to establish a connection and exchange streams
of data.) TCP guarantees delivery of data and also guarantees that
packets will be delivered in the same order in which they were sent.
