CompTIA A+ Certification Core 2 (220-1102) - Power Protection

The video tutorial discusses the importance of power protection for computer systems, highlighting common power issues such as spikes and sags. It explains the role of surge suppressors in mitigating spikes and introduces uninterruptible power supplies (UPS) as a more comprehensive solution. The tutorial emphasizes the need for reliable power protection to prevent damage and ensure system stability.

Why do people often neglect power protection after buying expensive computer components?

• They believe power protection is unnecessary.

• They run out of budget after buying other components.

• They think power protection is included with the components.

• They are unaware of power protection options.

What is a common effect of a power sag on a computer system?

• It can lead to system reboots.

• It can increase the system's speed.

• It can permanently damage the hard drive.

• It can cause the system to overheat.

What is the primary function of a surge suppressor?

• To increase the voltage supply to devices.

• To enhance internet connectivity.

• To provide backup power during outages.

• To protect devices from voltage spikes.

Which feature is NOT typically found in a surge suppressor?

• Ethernet protection

• Battery backup

• On/off switch

• Trip alert

How does a UPS protect against power sags?

• By converting AC to DC power.

• By disconnecting the device from the power source.

• By using internal batteries to supply power.

• By storing excess power in capacitors.

What is the main advantage of a UPS over a surge suppressor?

• It requires no maintenance.

• It can be used with any type of device.

• It provides protection against both surges and sags.

• It is cheaper and more compact.

What is the typical duration a UPS can provide power during an outage?

• Indefinitely

• A whole day

• A few minutes

• Several hours
