Explanation:
Environmental systems include heating, air conditioning, humidity control, fire suppression, and
power systems. All of these functions are critical to a well-designed physical plant. A computer
room will typically require full-time environmental control. Changing any of these controls (when it
was set to its optimum values) will result in damage.
