GUARANTEED ACCURATE
ANSWERS |VERIFIED |COMPLETE!!
Wiring System - ACCURATE ANSWERS✔✔ Is a form of electrical
circuit.
Electrical circuit - ACCURATE ANSWERS✔✔ Is comprised of an
energy source, energy transfer medium and a load.
Energy Transfer Medium - ACCURATE ANSWERS✔✔ copper wire,
fiber optic cables and air in the case of radiated energy
Load - ACCURATE ANSWERS✔✔ receives the transferred energy
such as resistors, lights, speakers, motors, etc.
EMF (electromotive force) - ACCURATE ANSWERS✔✔ The force
that moves electrical energy.
Current or Current Flow - ACCURATE ANSWERS✔✔ The movement
of electrons through a circuit that is caused by the electromotive force or
voltage applied to the circuit.

,Inductance (L) - ACCURATE ANSWERS✔✔ Unit is the henry. It is the
property of a circuit that causes an opposition to any change of current
within the circuit. As electrons flow, a magnetic field is produced. The
magnetic force induces a change in voltage.
Grounding - ACCURATE ANSWERS✔✔ assures transmission of
electrical signals without interference from electromagnetic radiation
from other transmission lines and equipment. This interference, called
crosstalk, can happen from adjacent lines, motors, PCs, lights and other
devices.
Grounding electrode - ACCURATE ANSWERS✔✔ Connection to the
electrode should be less than 1 ft below the surface of the solid and the
electrode should extend at least 10 ft below ground.
Ground Loop - ACCURATE ANSWERS✔✔ Causes a current to flow in
the low resistance of the shield resulting in electromagnetic waves that
are picked up as noise through the wire.
66 block - ACCURATE ANSWERS✔✔ A punchdown block that
terminates 22 to 26 AWG solid copper wire. The 25 pair standard non
split 66 block contains 50 rows.
110 block - ACCURATE ANSWERS✔✔ To terminate on-premises
wiring in structured cabling. IDC or Insulation displacement contact
connector is used to terminate the twisted pair. The 110 allows for a
, much higher density of terminations, less crosstalk and higher
bandwidth data.
UF - ACCURATE ANSWERS✔✔ Cable can be buried into the ground.
Not approved for commercial use in NM. 340.10
Balun - ACCURATE ANSWERS✔✔ A means of matching an
unbalanced antenna or transmission line to a balanced transmission line
or antenna (Usually have a transformer in them)
Bus Topology - ACCURATE ANSWERS✔✔ All nodes are connected to
a single shared communication line
Ring Topology - ACCURATE ANSWERS✔✔ Topology where the
computers are connected on a loop or ring.
Star Topology - ACCURATE ANSWERS✔✔ A topology with one
central node that has each computer or network device attached to the
central node. All data first goes into the central node and then is sent out
to its destination.
Transducer - ACCURATE ANSWERS✔✔ A device that converts energy
from one form to another
