Power line monitor

B.
Surge protector

C.
Shielded cabling

D.
Regulator

Explanation:
D: When clean power is being provided, the power supply contains no interference or voltage fluctuation. Mechanisms should be in place to detect unwanted
power fluctuations and protect the integrity of your data processing environment. Voltage regulators and line conditioners can be used to ensure a clean and
smooth distribution of power. The primary power runs through a regulator or conditioner. They have the capability to absorb extra current if there is a spike, and to
store energy to add current to the line if there is a sag. The goal is to keep the current flowing at a nice, steady level so neither motherboard components nor
employees get fried.
A is incorrect because power line monitors are employed to detect frequency and voltage amplitude changes. Interference interrupts the flow of an electrical
current, and fluctuations can actually deliver a different level of voltage than what was expected. Each fluctuation can be damaging to devices and people. In order
to effectively monitor frequency and voltage amplitude changes, you should understand what they are. Power excess can be described as a spike, which is
momentary high voltage, or a surge, which is prolonged high voltage. Power loss can be experienced as a faultmomentary power outageor a blackout
prolonged, complete loss of electric power. A sag or dip is a momentary low voltage condition, from one cycle to a few seconds. A brownout, also a type of power
degradation, is a prolonged power supply that is below normal voltage. Finally, an in-rush current is an initial surge of current required to start a load.
B is incorrect because a surge protector is used to move excess voltage to ground when a surge occurs. A surge is a prolonged rise in voltage from a power
source. Surges can cause a lot of damage very quickly. A surge is one of the most common power problems and is controlled with surge protectors. A surge can
come from a strong lightning strike, a power plant going online or offline, a shift in the commercial utility power grid, and electrical equipment within a business
starting and stopping. Most computers have a built-in surge protector in their power supplies, but these are small surge protectors and cannot provide protection
against the damage that larger surges (say, from storms) can cause. So, you need to ensure all devices are properly plugged into larger surge protectors, whose
only job is to absorb any extra current before it is passed to electrical devices.
C is incorrect because shielded cabling should be used for long cable runs and cables that run in buildings with fluorescent lighting or other inter ference
mechanisms. Fluorescent lighting gives off radio frequency inter ference (RFI), which is disturbance to the flow of electric power while it travels across a power
line. We could rip out all the fluorescent lighting in our buildingsor we can use shielded cabling where fluorescent lighting could cause a problem. If you were to
climb up into your office’s dropped ceiling and look around, you would probably see wires bundled and tied up to the true ceiling. If your office is using fluorescent
lighting, the power and data lines should not be running over, or on top of, the fluorescent lights. This is because the radio frequencies being given off can interfere
with the data or power current as it travels through these wires.
