  Common Ethernet speeds are 10 Mbps, 100 Mbps, and 1 Gbps -- often
called 1000 Mbps; in big LAN backbones, 10 Gbps is getting common and a
40 Gbps standard was recently ratified.

  I expect that your Comcast service actually provides something less
than 10 Mbps -- possibly a LOT less.  But the slowest standard Ethernet
speed is 10 Mbps, so that's what the connection between your computer
and your cable modem uses.  The cable modem buffers data inbound and
outbound to accomodate the difference between the Ethernet side and the
cable side.
