Full-duplex is a communications channel which allows data to be sent in both directions simultaneously. On a network that uses full-duplex communication, an example would be a computer sending data on the line while another is receiving data at the same time.

Correct Option(s):

d) Full-duplex

Incorrect Option(s):

a) Full-demo - This is not a term related to communication processes within a network.
b) Half-duplex - Half-duplex is a communication channel that allows data to be sent in both directions, however not simultaneously. The data is sent one way at a time.
c) Peer-to-peer - This is a type of network where each computer has the same responsibilities and capabilities. In this case a server is not needed as all computers are treated as equals, and are able to share and communicate resources between each other.

To me, "full-demo" doesn't even seem to make sense. WRT software, how can a "demo" be "full"?
