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 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

The original meaning of the socket is "hole" or "socket". Here as a 4BDS UNIX process communication mechanism, take the latter meaning. The socket is very similar to a telephone socket. Take a national telephone network for example. Telephone calls are equivalent to each other 2 processes of communication, the area cod

TCP fails to retransmit, UDP does notNext, let's look at the socket programming that works in the application layer:Sockets are a way of communicating with other programs using the standard UNIX file descriptor (descriptor). Sockets can be thought of as communication connection endpoints for two p

Reprinted from Http://dotnet.chinaitlab.com/ASPNET/731870.html Many people think that the server socket in the network application should not use synchronous sockets. Yes, in most cases it is, but there are also scenarios where we might get more results with a sync socket. We can consider using synchronous sockets for the following two scenarios. One, the number of clients is less than: A smaller number ref

Hp-socket is a common set of high-performance Windows Socket component packages that contain server-side components (IOCP models) and client components (Event Select model), which are widely used in Windows platform TCP communication systems. Hp-socket the communication layer is fully encapsulated, the upper application does not need to pay attention to any detai

Network sockets are also called an Internet socket, which in English is a Web socket. In a network, a socket plays a role as a socket, an endpoint that can be connected to other sockets in the network. Sockets allow two of processes to communicate, which may run on the same machine or on different machines. More preci

Socket programming refers to a complete set of API programming about sockets, not just the use of socket () system calls, but also a complete set of functions around this system call. Here we will start from the basics and learn how to write the socket program initially. host byte order and network byte order To learn about s
