11. Cable Toner12. Continuity Tester- an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made 13. Category 5e/6 cable- is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards 14. Binder Groups- Cable pairs are typically arranged under the cable sheath in binder groups 15.
Calculate the impedance by the measured values of voltage and current from the oscilloscope. Also calculate the impedance from = − C. Answer: Impedance, Z = 5∠0 34.65 60.48°) = 173.25 - 60.48⁰ = 85.37 Ω - j150.76 Ω Again, XC = 1/ = 1/ (6280 x 10-6) = 159.24

A 17. D 18. A and D 19. C 20. B, C and D Electrical Circuit – an electrical device that provides a path for electrical current to flow Frequency – The cycles per second of alternating current, measured in Hertz Amplitude – the maximum difference of an alternating electric current or potential from the average value Phrase – is a position of a point in time on a waveform cycle Bit time – the time it takes for one bit to be ejected from a network interface card at a standard speed Encoding Scheme – a system used by computers to represent data as characters Unshielded twisted-pair – The word unshielded refers to the fact that UTP cables have no added shielding materials to prevent EMI problems Core- The light source on one end of the cable shines light into the core Cladding- surrounds the core, for the entire length of the cable, and reflects the light into the core Radio waves- work well for networking because as a waveform, radio waves can be changed (modulated) over time to send data.
