What's the main difference between bidirectional and directional sockets?
问题 Bidirectional means the data incoming and outgoing data flows over the same channel (sockets), in classical socket it is the case. For example you want to connect to a server: you create a socket, send and receive the data over the same channel. Is that not bidirectional? What's different to websockets (bidirectional), only that they are runnable on browsers? Is that the difference? Another question is what happens during bind() on serverside; is this used to say to the TCP-Stack
