What is a disadvantage of Mesh Topology?
Can get very expensive due to many cables
What is a characteristic of Circuit Switching?
Each connection has its own dedicated channel
Why is Ring Topology difficult to troubleshoot?

The Application Layer represents a user interface to the network and helps users run applications.
True
The Physical Layer in the OSI Reference Model is responsible for representing a user interface to the network.
False
The Data Link Layer is responsible for logical addressing.
False
IP addresses are used at the Network Layer, while MAC addresses are used at the Data Link Layer.
True
NIC addresses at the Data Link Layer uniquely identify network devices on the same local network.
True
