Socket is the network connection endpoint. I. Introduction to Network Knowledge Socket is the network connection endpoint. For example, when your Web browser requests the homepage of www.jb51.net, your Web browser creates a socket and commands it to connect to the Web server host of www.jb51.net, the Web server also listens to requests from a socket. Both ends u

SocketSockets are also commonly referred to as "sockets," which describe IP addresses and ports, and are a handle to a chain of communication, where applications usually make requests to the network through "sockets" or respond to network requests.Sockets originate from UNIX, and one of the basic philosophies of unix/linux is "Everything is file", and the file is operated with "open" "Read and Write" "Off"

of HTTP connection is that each request sent by the client requires a server to send a response. After the request ends, the connection is released. The process from establishing a connection to closing a connection is called "One connection ". The Internet Protocol (Protocol) An IP address is a 32-bit unsigned integer. IP addresses are mapped to Domain names through the DNS (Domain Name System) Database #!/usr/bin/- Chapter -= =, hostname, , addr# The address of google.com is 173.194.72.113
