What is the main difference between bidirectional and directional sockets?

Bidirectional means that incoming and outgoing data arrives on the same channel (sockets), in a classic socket it is. For example, you want to connect to a server: you create a socket, send and receive data on the same channel. Isn't that bidirectional?

What is different from websockets (bidirectional), only that they run in browsers? Is that the difference?

Another question: what happens during the time bind()on the servers; Is it used to implement the TCP stack of the OS to which the socket should be sent to messages on this port?
