- QUESTION 15 A Television broadcasting service uses a single coaxial cable with a bandwidth of 680 MHz to transmit multiple TV channels to their subscribers. Each TV channel is 6 MHz wide. How many channels can be carried if each channel has to be separated by a 1 MHz guard band?Coaxial cable has been around since local area networking was in its invented. The original designers of Ethernet picked coaxial cable as their "ether" because the coaxial cable is well it has high bandwidth capabilities and low and is easy to install. Coaxial cables are identified by their RG standard. Coaxial cable can have a or stranded core and impedance of 50, 75, or 92 ohms. The Coaxial has wire that carries the signal surrounded by a layer of and another concentric ; both the shield and the inner conductor run along the same axis. The shield also serves as a ground and should be grounded to be effective. Coaxial cable is still widely used for video applications; in fact, its use is increasing due to the greater demand for However, it is not recommended for data installations and is not recognized by the Standard for such.

- There are three different types of charges that AEP uses to determine the amount it will charge a household for electricity usage each month. The first type of charge is the “customer charge”, which is a flat monthly rate (adjusted annually) that each household is charged. A second type of charge is the “transmission service” charge, which reflects how much it costs the electric company to move electricity from the power generating plants to the different substations (before being distributed to the households). A customer’s fee for transmission service depends on the amount of electricity used by that individual household. The third type of charge is the “distribution service” charge, which reflects the cost to distribute the electricity from the local substation to the household. The distribution service charge is also based on the amount of electricity used by the individual household. Suppose that AEP charges a monthly fee of to each household as its customer charge; it charges…Microwave device is an equipment transmission in telecommunication system. Based on the appropriate diagram of a microwave communication system, explain the mode of delivery and frequency band used by the system.Explain the construction of Co-axial, UTP, and STP cables.

- Consider building a CSMA/CD network running at 10Mbps over a cable with no repeaters. If the signal speed in the cable is 106 km/sec and minimum frame size is 1500 bytes, then what is the cable length (km)?In Figure Z, S1 connects to Computer A with an Ethernet Cable. In the older days, you needed to be very specific regarding the Ethernet Cable that should connect from S1 to Computer A. (Hint: We are talking about Straight through vs. Crossover Cables.) What type of cable should be used to connect S1 and A? What about the cable connecting S1 and R1? What if R1 is directly connected to Computer A (without the switch). What about two computers connecting to each other directly through an Ethernet Cable? Search online to find out why do we not need to worry about whether the cable is Straight through or Crossover Cable when connecting devices these days?Select the statement that is false. UTP cable is unshielded. Twisting two pairs of wires results in both wire being less affected by external noise. Cat 5 cable is composed of four shielded twisted pairs of insulated wires. Increasing the number of twists per meter in the Cat 3 cable reduces crosstalk.
