Why would a network administrator choose to implement Gigabit Ethernet
from the backbone to the end user ?
higher bandwith provides high speed file transfer, maybe for a person who needs a high amount of bandwith because of the nature of his job i.e. computer graphics artist
On what type of network device are you likely to find serial 1/0
Router
What does IEEE 802.3 describe \?
Ethernet LAN type i.e. 802.3u Fast Ethernet
How many pins does an AUI port have?
15 pins
A repeater allows multiple hosts to be connected by taking an
incoming signal and generating a new, clean network signal.
Why doesnt the repeater simply amplify the incoming signal?
Because the signal would be amplified after its distortion/deterioration took place,
Making a large deteriorated signal and transmitting the deteriorated signal along the rest of the network.
Peer to peer and client server are 2 types of networks

How do you connect an AUI port on a Cisco 2500 router to a CAT 5 ethernet
cable?
Use a transceiver that converts an AUI to an RJ-45
