Ethernet can only send a packet one direction at a time (i.e. a packet can
not be coming to the NIC and leaving the NIC at the same time) if that
happens you have whats called a media collision in networking. So GbE
allows you to send 1 Gig of data per second, any amount of that 1 Gig can
be going either way.

Wire speed is that of how much data it can send per second. In this case 1
Gig.
