What is the Physical Layer?
The part of a network where data is sent when it must end up on another network
What is the Default Gateway?
Which two OSI model layers have the same functionality as a single layer of the TCP/IP model?
What are the Physical and Data Link Layers?
(They make up the Network Access Layer of teh TCP/IP Model)

What is Encryption?
Name 2 reasons that makes fiber preferable to copper cabling for interconnecting buildings
1) Longer Distances
2) Faster response/ greater bandwidth
3) Less susceptible to EMI
These define how messages are exchanged between the source and the destination.
