Exercise 4.1.1
Why are standards so important for NICs, connectors, and media? Use your textbook and Internet research to justify your answer.
So that NIC’s on different service providers can communicate with each other.
Exercise 4.1.2
The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt. Why is this so low when the capacity for transmitting electricity on the copper wire is so high? Use your textbook and Internet research to support your answer.
Copper wire is used to power appliances and other devices so it has a high capacity for transmitting electricity.
Exercise 4.1.3
What are some applications of shielded copper cable? Why is the more expensive shielded cable used in these situations? Use your textbook or Internet research to support your answer.
Applicators can be steel reinforced concrete in buildings, elevators, high capacity radio transmitters, and more expensive cables lessen the changes of interference.
