BICSI INSTALLER EXAM 2025 QUESTIONS AND ANSWERS

American Wire Gauge (AWG) - ANS A system used to provide a standard reference for comparing various physical demensions of conductor materials. The greater the wire diameter the smaller the AWG value. Attenuation - ANS The decrease in magnitude or the power loss of a signal that propagates between two points, expressed in (dB) as the ratio of received signal to transmitted signal level. Bandwidth - ANS The information-carrying capacity of a system. Expressed in the range of analog frequencies (e.g. 0Hz to 1 MHz) that can be transported or processed by the system. Capacitance - ANS A property of conductors that allows storage of electrical charges when potential differences (voltages) exist between the conductors. Measured in farads (F). Crosstalk - ANS The unwanted transfer of a signal's electromagnetic energy from one or more circuits to other circuits. Impedance (Z) - ANS The total opposition to current flow is called ________. Measured in ohms. Inductance - ANS The property of an electromagnetic field built around a conductor that opposes any changes in current flow in a circuit, both AC and varying DC. The basic unity of inductance is a Henry (H).

Nominal Velocity of Propagation (NVP) - ANS A ratio of the speed of transmission along a cable relative to the speed of light in a vacuum. It is often stated in percentages. Resistance - ANS The property of a conductor to resist the flow of electricity through it. Expressed in ohms. Return Loss - ANS A ratio of the power of the outgoing signal to the power of the reflected signal. Expressed in decibels. Analog, Digital - ANS The information transmitted by an ICT system can originate in tow forms: ________ and ________. Megahertz - ANS Which of the following quantifies the bandwidth of a cabling system in a frequency range of interest? Full Duplex - ANS Communication that happens in two directions at the same time. Bit - ANS The basic unit of digital information Decibel (dB) - ANS The unit used to express system gain and loss. Frequency - ANS The number of cycles a signal is repeated in a period. Half Duplex - ANS Communication between two devices whereby transmission takes place in only one direction at a
