What device prevents power interruptions resulting in corrupted data?

A device that prevents power interruptions and protects against data corruption is an Uninterruptible Power Supply (UPS). It provides backup power through batteries during outages or fluctuations, allowing for safe shutdowns and continuous operation of critical systems. Additionally, some UPS models include surge protection features to safeguard equipment from voltage spikes. By ensuring a stable power supply, a UPS helps maintain data integrity and system reliability.
