CSIS-330 Chapter 4 Question and
answers already passed
telecommunications industry association - correct answer an organization
that develops standards that relate to telecommunications technologies
international telecommunications union (ITU) - correct answer United Nations
agency responsible for issues that concern information and communication
technologies
institute of electrical and electronics engineers (IEEE) - correct answer an
international, nonprofit organization for the advancement of technology related
to electricity
ISO - correct answer an international standards body that defines many
networking standards
manchester encoding - correct answer line code in which each bit of data is
signified by at least one voltage level transition
bandwidth - correct answer the capacity of a medium to carry data
throughput - correct answer the measure of the transfer of bits across the
media over a given period of time
latency - correct answer the amount of time, to include delays, for data to
travel from one given point to another
, electromagnetic interference - correct answer signals can distort and corrupt
the data signals being carried by copper media
crosstalk - correct answer a disturbance caused by electric or magnetic fields
of a signal on open wire to the signal in an adjacent wire
unshielded twisted pair (UTP) - correct answer most common networking
media; used for interconnecting network hosts with intermediate networking
devices, such as switches and routers
shielded twisted pair (STP) - correct answer provides better noise protection
than UTP cabling; combine techniques of shielding to counter EMI and RFI,
and wire twisting to counter crosstalk
coaxial cable - correct answer two conductors that share the same axis; used
to transmit electronic signals
wireless installations - correct answer coaxial cables attach antennas to
wireless devices
cable internet installation - correct answer cable service providers provide
internet connectivity to their customers by replacing portions of the coaxial
cable and supporting amplification elements
fiber-optic cable - correct answer physical medium that uses glass or plastic
threads to transmit data
cancellation - correct answer designers now pair wires in a circuit; when two
wires in an electrical circuit are placed close together, their magnetic fields are
the exact opposite of each other
