What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? - ANSWER Changing the infrastructure all at once would cause too many service disruptions. What is the difference between the fiber-to-the-node (FTTN) and fiber-to-thecurb (FTTC) topologies? - ANSWER An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises

Baseband signaling - ANSWER is predominant in Ethernet networks. two ways we can use a flow of energy to carry data - ANSWER Analog and digital Simplex - ANSWER A signal may flow in only one direction.
