Whether you care or not, Java Web applications use a thread pool more or less to process requests. The implementation details of the thread pool may be overlooked, but the use and tuning of the thread pool will need to be understood sooner or later.

The network application is divided into two parts: the client and the service side, while the socket class is the Java class responsible for handling client communication. This class enables you to connect to a server with a specified IP or domain

IO multi-channel model -- select, IO model -- select1. Trigger of IO multiplexing Model First, we will introduce the concept of "Trigger" in an I/O multi-channel model: 1 # There are two modes of horizontal triggering and edge triggering in linux

Java was originally introduced as a network programming language, which provides a high degree of support to the network, which makes the communication between client and server become reality, and in network programming, the socket is the most used.

This article mainly introduces the basic knowledge of python network programming. For more information, see John Goerzen, author of "python network programming Basics ". Part 1 underlying network learning Python provides all the methods to access

This article shares two python examples. python constructs icmpecho requests and implements network detector code. similar to the nmap function, python Sends icmp echo requesy requests. The code is as follows: Import socketImport struct Def

Raw socket has been used over the past few days, and some demo programs have been written in python, which is recorded here. First, let's look at a simple sniffer program: Copy codeThe Code is as follows:#! /Usr/bin/python# Code for linuxImport

Python 3: select-based event driver, pythonselect The basic principle of this function is that the select/epoll function will continuously poll all the sockets in charge. When a socket has data, it will notify the user process. Its Process When a
