The ideal operating humidity range is defined as 40 percent to 60 percent. Low humidity (less than 40 percent)
can produce what type of problem on computer parts?

A.
Static electricity

B.
Electro-plating

C.
Energy-plating

D.
Element-plating

Explanation:
It is important to maintain the proper temperature and humidity levels within data centers, which is why an
HVAC system should be implemented specifically for this room. Too high a temperature can cause
components to overheat and turn off; too low a temperature can cause the components to work more slowly. If
the humidity is high, then corrosion of the computer parts can take place; if humidity is low, then static electricity
can be introduced. This static electricity can short out devices and cause the loss of information. Because of
this, the data center must have its own temperature and humidity controls, which are separate from the rest of
the building.
Incorrect Answers:
B: Electro-plating is not caused by low humidity. Therefore, this answer is incorrect.
C: Energy-plating is not caused by low humidity. Therefore, this answer is incorrect.
D: Element-plating is not caused by low humidity. Therefore, this answer is incorrect.
