Answer:
d. All of the above
Explanation:
Physical layer is the lowest layer of the OSI reference model that deals with the setup of physical connection to the network and with transmission and reception of signals.
Full duplex (FDx) is a bidirectional type of communication system where two end nodes send and receive data signals at the same time, and a single carrier is simultaneously used for dual communication.
To send or receive data, the participating nodes in a Full Duplex system do not have to wait for a free carrier/medium. It employs a medium that has at least two internal channels - one for sending and one for receiving.
Based on the above explanations, options A, B and C are valid and are correct ways to accomplish full-duplex (FDX) digital communications on guided medium at the physical layer (OSI Layer 1). There all of them are correct.
Answer:
C) Router
Explanation:
In computer networking, the router's function is to stand in between diferent data lines and control the flow of data packets. When a packet arrives from one direction, it reads the address information in the header to determine its direction. Note that the data lines will contain different IP addressing scheme, so considering the scenario in the above question, since the offices use different IP schemes, a router will serve the purpose of directing data packets to allow communication.
