What does a UPS provide during a power failure?

A UPS, or Uninterruptible Power Supply, is specifically designed to provide emergency power to devices during a power failure. It contains a battery that kicks in when the main power source is lost, allowing connected devices to continue operating for a limited period of time. This functionality is crucial for maintaining operations during outages, preventing data loss, and allowing users to save their work and safely shut down equipment when necessary.

While some options may seem relevant, they do not accurately describe the role of a UPS. Increased power supply for all devices implies an upgrade or additional power beyond normal levels, which is not what a UPS does. Similarly, unlimited power backup is misleading, as a UPS only provides power for a finite amount of time, depending on its capacity and the load it supports. Data recovery options suggest a process for recovering lost or corrupted data, which is outside the scope of what a UPS is designed to do.
