What is the physical topology?

1. groups the hosts based upon the network branch they are on
2. defines the way devices connect to a network
3. describes how hosts access and communicate on the network
4. defines the hosts in network location, not physical location

What is a logical topology?

1. The actual design layout of a network
2. he way the topology is shaped
3. The topology that makes sense
4. describes how hosts access and communicate on the network

What is Half Duplex communication?

1. When data flows in both directions at the same time,
2. Broadband technologies
3. data can be sent and received at the same time
4. When data flows in one direction at a time,

What is a full duplex?

1. When data travels over a network
2. When data can travel both directions at the same time

Contention-based access

1. processes more overhead than the controlled access method do
2. It scales very well under heavy media use.
3. It is a nondeterministic method
4. It has mechanisms to track the turns to access the media.
