at the same time
Half Duplex correct answers Communication occurs one way. Talking or listening occurs one at
a time
Store and Forward correct answers Receive a message, store it, then forward it
Border Gateway protocol correct answers COnnects two separate networks
internet correct answers A network of networks
Interoperability correct answers We can talk to each other even if we have different protocols.
Creates a standard
Network correct answers 2 or more nodes connected via two or more nodes
End Systems correct answers -Can be server or client
-Located at the edge of the network
-Use communication links that are both wired and wireless
Client Server correct answers Runs some program that request services
Server correct answers Listens for a request and provides a service
