This article mainly introduces "what is the difference between TCP and UDP protocols". In daily operation, I believe many people have doubts about the difference between TCP and UDP protocols. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts about "what is the difference between TCP and UDP protocols". Next, please follow the editor to study!

UDP does not need to establish a connection before transmitting data, and the remote host does not need to give any confirmation after receiving the UDP message. Although UDP does not provide reliable delivery, UDP is the most effective way to work in some cases (generally used for instant messaging), such as QQ voice, QQ video, live streaming, etc.

TCP provides connection-oriented services. A connection must be established before data transfer, and the connection must be released at the end of the data transfer. TCP does not provide broadcast or multicast services. Because TCP should provide reliable, connection-oriented transmission services (the reliability of TCP is reflected in that TCP has three handshakes to establish a connection before transmitting data, and there are mechanisms of acknowledgement, window, retransmission, congestion control, and disconnection to save system resources after data transmission), it is difficult to avoid adding a lot of overhead, such as confirmation, flow control, timer and connection management. This not only increases the header of the protocol data unit, but also consumes a lot of processor resources. TCP is generally used in scenarios such as file transfer, sending and receiving mail, remote login, and so on.

At this point, the study on "what is the difference between TCP and UDP protocols" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
