Dear rodferna-ga,

4. Routing is a function of the network layer in the standard OSI
model.

5. Dissimilar networks are connected by gateways.

6. X.500 is a directory standard, not a network architecture.

7. FDDI is a LAN technology, not a topology. Arguably, "LAN" isn't
strictly a topology either, but it's closer to being one than FDDI is.
