Week 6 Notes

One thing that I found interesting about the readings and videos on computer networks was the matrushka doll-like nature of their organization. A PAN is part of a LAN, which is part of a WAN, and so on. As network communication becomes faster, will we really need the LAN? I guess it will still be important as an organizational and security level, but It seems that soon we will be just as connected to other computers in a WAN as we are in a LAN.
