An understanding of the following key
points should have been achieved:
- A network interface card (NIC)
provides network communication capabilities to and from a PC.
- Use a crossover cable to connect
between two similar devices, such as switches, routers, PCs, and
hubs.
- Use a straight-through cable to
connect between different devices, such as connections between a
switch and a router, a switch and a PC, or a hub and a router.
- There are two major types of LANs,
peer-to-peer and client/server.
- WANs use serial data transmission.
WAN connection types include ISDN, DSL, and cable modems.
- A router is usually the DTE and
needs a serial cable to connect to a DCE device like a CSU/DSU.
- The ISDN BRI has two types of
interfaces, S/T and U interfaces. To interconnect the ISDN BRI port
to the service-provider device, a UTP Category 5 straight-through
cable with RJ-45 connectors, is used.
- A phone cable and an RJ-11 connector
are used to connect a router for DSL service.
- Coaxial cable and a BNC connector
are used to connect a router for cable service.
- Rollover cable is used to connect a
terminal and the console port of an internetworking device.
