E
thernet cabling is an important discussion, especially if you are plan-
ning on taking the Cisco CCNA exam. The types of Ethernet cables available
are straight-through cable, crossover cable, and rolled cable.
If you are studying for your CCNA exam, you better know your Ethernet
cabling types!
Straight-Through Cable
This type of Ethernet cable is used to connect:
Host to switch or hub
Router to switch or hub
Four wires are used in straight-through cable to connect Ethernet devices.
It is relatively simple to create this type; Figure 1.15 shows the four wires
