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

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

Communication protocols for TCP/IP This section briefly introduces the internal structure of TCP/IP and lays the groundwork for discussing security issues related to the Internet. TCP/IP protocol groups are popular in part because they can be used on a wide variety of channels and underlying protocols such as T1 and X., Ethernet, and RS-232 serial interfaces.

UDP and TCP use port numbers to send and receive data simultaneously for multiple applications. Data is sent out through the source port and received through the target port. Some network applications can only use reserved or registered static ports, while others can use unregistered dynamic ports. Because UDP and TCP headers use two bytes to store port numbers, the valid range of port numbers is from 0 to

When the client needs to request some data on the database server, it needs at least three datagram to establish a TCP connection, three datagram to send and confirm a small amount of data, and three to close the connection. However, if you use UDP, you only need to issue two data packets to achieve the same effect. UDP does not require the client to establish or disable connections to the server. The clien

DNS uses the TCP protocol or UDP protocol. It is recognized that DNS uses both UDP and TCP port 53, this single application protocol uses two transmission protocols at the same time in the TCP/IP stack is also an alternative. However, few people know under what circumstances DNS uses the two Protocols. First, we will briefly introduce TCP and UDP. TCP is a connec

TCP and UDP are important in network transmission, as well as in Android development.First look at what TCP and UDP are.What is TCP?Tcp:transmission Control Protocol Protocol TCP is a connection-oriented, reliable, byte-stream-based transport layer (Transport layer) communication protocol, which is provided by the IETF RFC 793 description (specified). In the simplified computer network OSI model, it accompl

UDP Protocol Introduction UDP transmission is very similar to IP transmission. You can regard UDP as an interface that exposes the IP protocol to the transport layer. UDP also transmits data packets in the form of "Best Effort", so UDP is also unreliable ). So why do we need

I. Overview TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two different communication protocols at the transport layer in the network architecture TCP/IP model. TCP: Transmission Control Protocol, a connection-oriented protocol that provides a reliable full-duplex byte stream for user processes. The TCP set interface is a type of streamsocket interface. UDP: User Datagram Proto

The difference between TCP protocol and UDP Protocol (RPM)First we find out that the TCP protocol and the UCP protocol and the TCP/IP protocol, many people confused, has always been the TCP/IP protocol and the difference between the UDP protocol, I think it is not fundamentally clear network communication!The TCP/IP protocol is a protocol cluster. It includes a lot of protocols.

1. Overview Some common applications written using UDP include DNS (Domain Name System), NFS (Network File System), and SNMP (Simple Network Management Protocol) Provides typical function calls for UDP client/server programs: 2. recvfrom and sendto Functions Two functions are similar to the standard read and write Functions, but three additional parameters are required. # Include The first three parame

After the standard UDP client has opened a set of interfaces, it generally uses the sendto and recvfrom functions to send data. Recently, we can see that the ntpclient Code uses the direct method of the send function, so we have analyzed it, in the past, UDP sent data in two ways for you to choose from, by the way, UDP connect usage will be clearly explained.Meth

TCP byte stream and UDP datagram "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
