The correct answer is True.
Explanation
When we must solve a multiple-choice test or exam, in most cases, we are asked to select only one choice from four or more options. This means we need to know which is the correct answer from the options given to obtain a good grade. Due to this, we must be very precise when responding and paying attention to details because many times the answers are very similar, but only one contains all the elements that answer the question.
One of the most used methods to do this is "eliminating answers" this means we discard answers that we are sure are not possible answers by crossing out these and leaving only the correct answer or a few possible correct answers, in this case, we will need to analyze the remaining answers to select the most appropriate. So, the correct answer is True.

A surge suppressor, which is also commonly known as a surge protector, is an important equipment that helps prevent damage to electric components from an unexpected increase of voltage. Let’s assume that you are living in a county where the effective utility voltage is between 110 to 120 volts. Assume that the accepted peak voltage should not be anything higher than 170 volts. If there is a surge and this surge reaches peak levels of 170 volts and higher, surge suppressors should jump in and prevent the peak AC voltage from going above the threshold.
People tend to confuse line conditioners and surge suppressors. While surge suppressors protect components from surges, line conditioners are built to make up for the loss of voltage from the lines. It does so by storing some power energy. This stored energy can later be modified and used when the volts drops to the desired 110 volts.
A UPS has DC battery power that provides battery backup power when the electricity goes off or when the levels of voltage drop significantly. When the electricity goes off means that the voltage is at 0 volts and it is the work of the UPS to kick its backup power in.
There are some function which can be performed with database but not with a spread sheet, these functions include:
1. Enforcement of data type.
2. Support for self documentation.
3. Defining the relationship among constraints in order to ensure consistency of data.
