1. You have created a simple electrical circuit with a battery, wires, and a light bulb. Which of the following is true about this circuit? (Choose two answers.) b,c 2. A PC NIC and a switch port create one electrical circuit to use when sending data. The sender creates a (maximum) 1-volt electrical signal with a frequency of 1000 hertz. Which of the following facts are also true? (Choose two answers.) a,c 3. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. Which of the following tasks is a function done by the transmitter? (Choose two answers.) a,c 4. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. The transmitter uses a simple encoding scheme that uses a higher amplitude to encode 1 and a lower amplitude to encode 0, sending 1 bit in each bit time. The bit rate is 2000 bits per second (2000 bps). Which of the following is true on this circuit? d 5. Two nodes use an encoding scheme that cannot use one circuit to both send and receive data at the same time. The link physically contains two wires. Which of the following is a possible option to allow both nodes to send data? b 6. UTP cables can have up to eight wires inside the cables. Which of the following is the most likely reason why EMI from one wire does not affect the electrical behavior of another wire inside the same cable? b 7. Which of the following facts are in common between both of the Ethernet standards discussed in this chapter, 10BASE-T and 100BASE-T? (Choose two answers.) a,b 8. Which of the following answers best describes the definition of a cabling pinout? a 9. A PC NIC connects to a switch port using 100BASE-T. Which of the following is true about what happens on that link? a 10. With a fiber-optic cable, the core of the cable, through which light passes, is
