Explanation

A UPS (Uninterruptible Power Supply) provides battery backup power to keep devices running during a loss of power, preventing shutdowns and data loss. Power load refers to the amount of electrical power used, not a device or method. PDU (Power Distribution Unit) distributes power but does not provide backup during outages. Voltage is the measure of electrical potential, not a solution for power loss. Only a UPS ensures continuous power during an outage.
