I have learned a lot of stuff I did not know before from this thread,
so I think I can answer that.
There must be a layer of software that listens at the port. When it
receives a packet, it can tell which client sent the packet (host and
port number). It uses that to look up which socket is handling that
particular connection, and passes it as input to that socket.
Therefore each socket only receives its own input, and is not aware of
anything received for any other connection.
Not a technical explanation, but I think it describes what happens.
