Java NiO channels are similar to streams, but are somewhat different: The data can be read from the channel, and the data can be written to the channel. But stream reads and writes are usually one-way. Channels can be read and written

The Socketchannel of Java NiO is the channel that connects TCP network sockets. There are two ways to create:1. Open a socketchannel and connect to a server on the network2. When Serversocketchannel receives a connection, Socketchannel creates aOpen

One. Select and Epoll First we define the concept of a stream, a stream can be a kernel object that can be used for I/O operations, such as files, Socket,pipe, and so on. Whether it's a file, a socket, or a pipe, we can think of them as a

The program written in this project is to communicate with the remote socket, use the accept to accept the long-distance connection request, has been in the program to accept used are blocking mode, received a new connection request, the creation of

And the first part of the previous article, the text is to help others or their own ideas, rather than the so-called source analysis, want to analyze the source code, or direct debug source is the best, see any document and books are the worst.

Python network programming--io multiplexing EPOLL1, kernel Epoll model explainedThis section refers to the http://blog.csdn.net/mango_song/article/details/42643971 blog and organizesFirst, we define the concept of flow, a stream can be a file,

This blog post focuses on how I/O works at the bottom. Readers of this article are eager to understand how Java I/O operations are mapped at the machine level and what the application runtime hardware does. Assume that you are familiar with basic

First we define the concept of a stream, a stream can be a kernel object that can be used for I/O operations, such as files, Socket,pipe, and so on. Whether it's a file, a socket, or a pipe, we can think of them as a stream. Now we'll talk about the

Five communication models of the operating system 1. Blocking I/O Is our common socket, the listening port receives the message to process, and returns the result to the client Waits until the I/O operation is complete and does not give control to

Reprint Please specify the Source: Jiq ' s technical BlogIntroductionNIO, or new IO, was introduced in JDK1.4 to improve IO speed. It is important to note that Javanio is not completely non-blocking IO (no-blocking io) because some of these channels

First, define a concept: Each TCP socket has a sending buffer and a receiving buffer in the kernel, the full duplex mode of TCP and the Sliding Window of TCP depend on the two independent buffers and the filling status of the buffer. The receiving

This article and two other related articles explain some issues in Windows Sockets programming. This article describes blocking. Other issues include Windows Sockets: byte sorting and Windows Sockets: conversion string. If you use the CAsyncSocket

File operations, as the name implies, is the existence of files on the disk for various operations, text files are read and write.1. Procedures for document Operation(1) Open the file, get the file handle and assign a value to a variable(2)

TCP protocol (theoretical) 1. What is different from UDP is that TCP provides a connection-oriented and reliable byte stream service. It is easy to understand connection orientation, that is, the two sides need to establish a connection before
