socket interface

What is socketA socket interface is an API of a TCP/IP network. A socket interface defines many functions or routines that can be used by programmers to develop applications on a TCP/IP network. To learn TCP/IP network programming on the internet,

This article introduces a basic knowledge about how data packets are transmitted and exchanged in routers, as long as you understand this, it will help you to configure a good network environment. First, the problem of input 1, the original set of

What is a socketThe socket interface is a TCP/IP network Api,socket interface that defines many functions or routines that programmers can use to develop applications on a TCP/IP network. To learn about TCP/IP network programming on the Internet,

Two programs on the network realize the exchange of data through a two-way communication connection, one end of which is called a socket. The original meaning of the socket is "hole" or "socket". As a BSD Unix process communication mechanism, take
