Hey SO

Doing a some practice questions for exam tomorrow can't figure out this one

What is the minimum number of socket port(s) required for a TCP server to connect a TCP client for communication?

Surely its just two right? one for the server one for the client, but this seems to obvious. My mates thinks TCP uses two ports at the server end for for data in and one for data out.

thanks in advance
