Done with Classes

I just finished my Networking final. So much studying. Did alright except for one question on Cyclic Redundancy Checks I think I missed. As far as the stack goes though, with frames going across the wire, being taken in by the NAT at the Link layer, getting repackaged into a different frame to the next MAC address and routed to the Dest IP address where the datagram is shed at the transport layer and the message is pushed (through a socket) up to the application layer. I think I did pretty darn good. :D
