TCP-UDP Transport Layer Protocol
TCP and UDP are the transport layer protocols of the TCP/IP protocol family: 1. TCP: connection-oriented: the process of creating a connection, communication between the two parties, and closing the connection. The connection is not created, non-point-to-point communication: one-to-one, not one-to-many; reliable: ensure that the sent information is complete and accurate; otherwise, re-transmission; www.2cto.com 2, UDP: for non-connection: that is, you do not need to create a connection. When sending information, no matter whether the destination has a point or multiple points of communication: that is, one point or multiple points, the broadcast is not reliable: The sent information is not guaranteed to arrive completely and accurately.
