"TCP is a stream-mode protocol and UDP is a datagram-mode protocol". I believe you are familiar with this sentence ~ However, what is the difference between "stream mode" and "data packet mode" in programming? The following is my understanding for your reference only! 1. TCP stands for a metaphor for TCP. you have a reservoir in your house. you can pour water in it. there is a faucet in the reservoir. you can put the water in the pool through the fauc

TCP the difference between protocol and UDP protocol first, let's get this straight. TCP agreements and UCP Agreement and TCP/IP agreement, a lot of people are confused, has always been said TCP/IP Agreement and UDP the difference between the protocols, I think it is not clear from the nature of network communication! the TCP/IP Protocol is a protocol cluster. It includes a lot of protocols.

first to understand the next UDP UDP is the abbreviation of Userdatagram protocol, the Chinese name is User Datagram Protocol, is a connectionless transport layer protocol in the Reference Model of OSI (open System interconnection, open Systems Interconnection). Provides a transaction-oriented, simple, unreliable information delivery service, and IETF RFC 768 is the formal specification of

This time, we will summarize the UDP and IGMP in the IP layer. UDP is a simple datagram-oriented transport layer protocol that provides unreliable services: It adds the application data to the UDP header and then sends it to the IP layer, but they cannot be guaranteed to reach their destination. The application must be concerned with the length of the IP datagram

parties.Difference Between TCP and UDP: 1. based on connection and no connection 2. requirements on system resources (more TCP and less UDP) 3. stream mode and datagram Mode 4. TCP ensures data correctness, UDP may cause packet loss, and TCP ensures data orderConnection-free: Connection and less onless are common terms in network transmission. Their relationship

In the application process of UDP protocol, we found the advantages of UDP socket to facilitate access to servers and clients. So what is UDP socket? Now let's give a brief introduction. UDP socket UDP provides an end-to-end service different from the TCP protocol. In fact,

1. The role of the UDP protocolThe IP protocol cannot differentiate multiple applications on the same host system. UDP uses ports to identify different applications on the same host.The process ID cannot be taken to identify the cause of the different applications:1) The process ID assignment and destruction of the application in the system is dynamic and the sender cannot determine what the application's p

Directory Data UnitFeaturesImplementationRequirementsUDP Header FormatClient illustration for sending UDP requests Data Unit The data unit protocol transmitted by UDP is UDP packets or user datagram. Features UDP is connectionless, that is, no connection is required before sending data.

TCP and UDP are important in network transport and are equally important in Android development. First let's take a look at what TCP and UDP are. What is TCP? Tcp:transmission Control Protocol Transmission Control Protocol TCP is a connection-oriented, reliable, byte-throttling transport layer (Transport Layer) communication protocol, by the IETF RFC 793 description (specified). In the simplified compute

Introduction to TCP/IP protocol Communication protocol for TCP/IP This section briefly introduces the internal structure of TCP/IP and lays the foundation for discussion of Internet-related security issues. The TCP/IP protocol group is popular in part because it can be used on a variety of channel and underlying protocols such as T1 and X.25, Ethernet, and RS-232 serial interfaces. Specifically, the TCP/IP protocol is a group of protocols that includes the TCP protocol and the IP Protocol, t

I was just beginning to touch the Linux socket programming, while the edge of the understanding of UDP socket programming, my question is that the server does not specify the IP address, the client's destination IP address is 127.0.0.1, so you can communicate? Is it not possible to test under the same host? If the server defaults to the IP address of the machine, then when server is turned on, enter 127.0.0.1: (corresponding port) in the browser to ge

A chat room is required to receive and send messages at the same time.The following code uses two threads to process the sending and receiving of information. The transmission of information over the Internet uses the UDP protocol. This method does not need to establish a connection, so it is more efficient, but is due to Yongji where the connection, so there will be packet loss of security.ImportJava.io.BufferedReader;ImportJava.io.InputStreamReader;
