A _________ is a rule or set of rules intended to ensure safety during the installation and use of
materials, components, fixtures, systems, premises, and related subjects. - ANS-Code - A code

A drawings - ANS-Architectural drawings show a plan (top) view of each floor in a building. They
include all aspects of the physical construction of the buiding, which provide the detail for such
items as wall types, elevations, rated construction (fire and smoke), reflected ceiling plans,door
hardware schedule, exact floor penetration dimensions, cabinetry, and furnishings. If the
architect employs interior designers, their work will be reflected on these drawings.(ITSIMM,

AHJ - ANS-Abbreviation of authority having jurisdiction. The building official, electrical inspector,
fire marshal, or other individuals or entities responsible for interpretation and enforcement of
local building and electrical codes. (ITSIMM, page A-1 to A-2) 02_PROFESSIONALISM AND

Alternating and direct currents are different in many ways. One way is their directionality/polarity.
Which of the two flows only in one direction? - ANS-dc: direct current (ITSIMM: Pages 1-2 to

American Wire Gauge (AWG) - ANS-Standard reference for comparing various physical
dimensions of conductor materials
Generally accepted worldwide
smaller numbers = Large wires(Fewer drawing steps)
Larger numbers = Smaller wires(More drawing steps)

An electric device draws 2.5 A from a 220 V source. What is the approximate resistance of the
heating element? Provide the formula and the answer. - ANS-V =IxR
220 = 2.5 x R
, 220 ÷ 2.5 = 88 ohms
Analog Signal - ANS-A signal in the form of a wave that uses continuous variations of a physical
characteristics over time (ex. Voltage amplitude, frequency) to transmit information. Analog
transmission uses continuously varying electrical signals that directly follow or are similar to the
changes in loudness (amplitude) and frequency (tone) of the input signal (e.g., human voice)
(ITSIMM, page 1-6) - 03_TRANSMISSION
Attenuation - ANS-The decrease in magnitude or the power loss of a signal that propagates
between points, expressed in decibels (dB), as the ratio of received signal to transmitted signal
level. See also insertion loss. (ITSIMM, page 1-17) 4_INTRODUCTION TO COPPER
Balanced Twisted-pair - ANS-A type of wiring in which two conductors of a single circuit are
twisted together in order to cancel electrical interference. (ITSIMM, GL-4) 4_INTRODUCTION

Bandwidth - ANS-Bandwidth represents the information carrying capacity of a system. It is
typically expressed in the range of analog frequencies (e.g., 0 Hz to 1 MHz) that can be
transported or processed by the system. (ITSIMM, page 1-9) - 03_TRANSMISSION
bel - ANS-A logarithmic ratio of analog signal strengths, named in honor of telephone pioneer
Alexander Graham Bell. A decibel is one-tenth of a bel. - 3_TRANSMISSION
Capacitance - ANS-1. The ability of an electronic component to store electrical energy. 2. The
opposition to a change in voltage. (ITSIMM, page 1-15) 4_INTRODUCTION TO COPPER
Category 5e UTP cable has transmission speed specified up to ______ MHz. - ANS-100
Balanced twisted-pair cabling channel performance table. (ITSIMM, page 1-24)

Code - ANS-A rule or set of rules intended to ensure safety during the installation and use of
materials, components, fixtures, systems, premises, and related subjects. Codes typically are
invoked and enforced through government regulation. (ITSIMM, page 3-52)

Codec - ANS-A device that converts analog data to digital format for transmission over digital
media. (ITSIMM, page 1-8) - 03_TRANSMISSION
Crosstalk - ANS-The unwanted transfer of a signal's electromagnetic energy from one or more
circuits to other circuits. (ITSIMM, page 1-25) 4_INTRODUCTION TO COPPER
Current (I) - ANS-The flow of electrons in a conductor; measured in amperes. (ITSIMM, page
