Lots of interesting things happen in between your computer and Google's servers - like ISPs exchanging routing information using BGP, so the routers can determine a route through each different AS (provider/transit network) it has to go through to actually Fong the machine with that IP, and the kinds of physical and data layers it goes through (cable or DSL, fibre, and Ethernet, SONET/SDH, maybe tunnelling over MPLS at some point) etc.
