function boh as client and server on each one. it's purpuse to send and receive files. The question is:
If the program on Computer A sends a file to computer B using port n, can it accept connection from Computer B

Yes, the port is only "consumed" on the receiving end and even then, you can have more than one connection on a given port.  As you call the listen() function on the receiver, it will hang until a connection comes in.  Then you call accept() to complete the connection.  If you process the data in a thread, your main loop can go back and keep listening and accepting more incoming connections.  The use of the port is limited to having one listener program on a given port.
