Network News Transfer Protocol (NNTP) allows TCP/IP users to perform which of the following? - Answer Download news articles. Which TCP/IP application distributes news articles read from a central database? - Answer Network News Transfer Protocol (NNTP). Which name resolution technique dynamically resolves Windows host names to IP addresses? - Answer ...

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. A commercial radio station uses simplex communication, because listeners cannot transmit radio signals back to the station. Half-duplex - Answer Signals may flow in either direction, but not simultaneously. For example, a two-way radio allows only one user to speak at any one ...

When pressure testing a drop system to check for leakage, What must be done before applying the test signal? Answer The technician must isolate the drop system from the hybrid fiber/coax (HFC) network by disconnecting the drop at the distribution tap. Why do some leakage detection systems utilize a leakage carrier modulated with a tagging signal? Answer To avoid false detection of leaks. When all three sections of a pulse code modulator (PCM) are combined, what function can be performed? A...

According to SCTE- and NCTA- recommended trunk system map symbols, fiber-optic cable is represented by Answer Double arrows within a small circle on a solid line. The forward path signal in a traditional tree-and-branch architecture Answer originates at the headend and is transmitted downstream through coaxial trunk cable and trunk amplifier. In a HFC network, Answer Processing equipment in the headend converts the forward RF signal to a light signal. During aerial plant construction, A...

What is the difference between the FTTN and FTTC topologies? Answer An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. What are the three categories of the fiber-optic cable used to identify the location of the fiber in the network? Answer Truck, branch, and drop Which type of fiber topology used in a PON places the PON splitters at the headend while providing one designated fiber for every customer premise? Answer Home-run Which PO...

Which of the following will strengthen signals as they move farther away from the headend through the trunk express system? Answer B) Distribution amplifiers. Which of the following describes a carrier wave? Answer B) A wave with a much higher frequency than the input signal. Which of the following describes modulation?
