• C. memory
• D. UPS

Answer 1

Answer:

D. UPS

• A UPS (Uninterruptible Power Supply) is a device that provides uninterrupted power to computers, servers, and other electronic devices during a power outage.

• A UPS can quickly switch to battery backup in the event of a power outage, giving the equipment enough time to operate and safely shut down.

There are three main types of UPSs:

Offline/Standby UPS:

• This is the most commonly used and least expensive UPS.

• It switches to battery backup only when there is a power outage.

• It is suitable for general-purpose applications such as computers.

Line-Interactive UPS:

• This is an improvement over offline UPS.

• It has a system for controlling voltage fluctuations.

• It corrects small voltage fluctuations without switching to an inverter.

Online UPS:

• This is the best and most expensive UPS.

• In this, the devices always receive power from the inverter.

• The incoming AC current only charges the battery.

• Therefore, the devices will continue to operate without any change in the event of a power outage.

• It is used for servers and important data centers.
