through socket

One, socketSockets are objects that provide the current portability standard for a network application provider on a specific network protocol (such as TCP/IP,ICMP/IP,UDP/IP, etc.). They allow programs to accept and connect, such as sending and receiving data. In order to establish a communication channel, it is extremely important for each endpoint of a network communication to have a socket object.Sockets are part of the core of BSD Unix systems, an

Java socket packet communication (I) socket establishment, socket Packet Java socket packet communication (I) socket Establishment Today, I will share with you how to use socket for communication in java. Let's take a look at TCP/

Assuming that the TCP socket server is already established and listening to the client's connection, the client can initiate the connection through the socket class. After the client initiates a connection request, it passively waits for a response from the server. This class is also located in the java.net package, which contains many methods for establishing connections, manipulating data flows, and so on

Socket-series socket server-how to communicate with the client, socket serverThe above sections have introduced the working steps of ServerSocket and Socket respectively, and analyzed their operating principles from the application layer to the bottom layer of the system. We have understood their respective parts. Now

Socket series What is socket and socket Series1. What is socket?Socket is the intermediate abstraction layer for communications between the application layer and the TCP/IP protocol family. It is a group of interfaces that the application layer can send and receive data by c

BYTE order: Host byte order: Different hosts have different byte order, x86: Small end, network byte order (network byte order): big-endian byte sequence; 0. What is a socketSockets are communications between network processes (network interprocess communication, also known as network IPC) interfaces that enable the process to communicate with other processes, whether on the same computer or not, as an abstraction of the communication endpoint, like a file descriptor Descriptor) is an abstract r

Introduction Java NiO, introduced from JDK1.4, provides a completely different way of working with standard IO. The NIO package (java.nio.*) introduces four key abstract data types that work together to address some of the problems in traditional I/O classes. 1, Buffer: It is a linear table structure that contains data and is used for reading and writing. It also provides a special class for I/O operations for memory-mapped files. 2, Charset: It provides the operation of a Unicode string

Java (Socket programming basics), socket programming BasicsI,Two main problems in Network Programming One is how to accurately locate one or more hosts on the network, and the other is how to transmit data reliably and efficiently after finding the hosts. In TCP/IP, the IP layer is mainly responsible for locating network hosts and routing data transmission. The IP address can uniquely identify a host on the

Image Description of the SOCKET protocol The original meaning of socket is "hole" or "socket ". Here we use the 4bds UNIX Process Information mechanism, take the latter meaning. Socket is very similar to a telephone outlet. Take a national-level telephone network as an example. The two sides of a telephone call are equ

processes running on different machines communicate with each other by sending messages to the socket. Each process is like a house, and the socket of the process is a door . sockets are the door between the application process and TCP , and application developers can control everything on the application layer of the socket, but cannot control the side of the
