General Programming: In a server socket accept() method what exactly happens. At low level how server sockets are different from client sockets?
Firstly, server sockets are generally bound to well known names (ports, in this case) and they establish themselves with
listen(). That is where the real difference happens, as client sockets establish themselves withconnect(). Callinglisten()on a socket causes the kernel’s tcp/ip implementation to begin accepting connections sent to the socket’s bound name (port). This will happen whether or not you ever callaccept().accept()simply gives your server a way to access and interact with the client sockets that have connected to your listening socket.
