  • U

    uninterruptible power supply (UPS)

    An uninterruptible power supply (UPS) is a device that allows a computer to keep running for at least a short time when the primary power source is lost. It also provides protection from power surges.

  • W

    wireless sensor network (WSN)

    A wireless sensor network is a group of specialized transducers with a communications infrastructure that uses radio to monitor and record physical or environmental conditions.

  • WUE (water usage effectiveness)

    WUE (water usage effectiveness) is a metric developed by The Green Grid nonprofit consortium to help data centers measure how much water a facility uses for cooling and other building needs.

  • Z

    zinc whiskers

    Zinc whiskers are tiny growths of elemental zinc that form on the surfaces of objects that are electroplated, or galvanized, with zinc.
