Which device provides backup power to connected devices during power loss?

• A. UPS
• B. Router
• C. Monitor
• D. Keyboard

Answer: (A)

Backup power during a power outage is provided by an uninterruptible power supply. It sits between the wall outlet and your devices, using its internal battery to keep-connected equipment running when the mains fail. This lets you save work and shut down safely, and many UPS units also offer surge protection and automatic voltage regulation to guard against spikes or dips in power. The runtime depends on how much load you connect and the battery size, but the key idea is that a UPS supplies power for a short period so you’re not left with abrupt shutdowns. A router, monitor, or keyboard by themselves don’t supply backup power. They need their own power from the wall and won’t keep other devices running when the power goes out.
