G.- Bandwidth
Bandwidth is the size of the "highway" through
which your internet data is passed. The more
information being passed through this highway,
the slower it goes. Just like Javier Prado at
rush hour, the more cars, the slower the going.
Your internet connection is your highway and
modems are freeway entrances and exits.
