span from 3 to 30 miles.: False
2. Ethernet is an example of a network layer protocol.: False, Ethernet is
Data-link

Transport
4. ___________ is an orderly close to a dialogue between end users.: Session
Termination
5. A local area network is:: a group of personal computers or terminals located in

to the final destination.: Network Layer
8. A(n) _________ is a network that uses the same technologies as the Internet
