- <p> Often, your personal computer is connected to the Internet
- through a <strong>modem</strong>. This <strong>modem</strong> takes the outgoing packets from all the machines connected to it
- and set the source address to a single value (such as "Home"). Incoming packets are then mapped back to the original
- machines. Pause the simulation and look at the packet information before and after it passes through the
- <strong>modem</strong>.
