Used to denote the total amount of electrical power being delivered to electronic equipment within a given rack. Often expressed in kilowatts (kW), this is often incorrectly equated to be the heat dissipation from the electrical components of the rack
Structure for housing electronic equipment. Differing definitions exist between the computing industry and the telecommunications industry
* Computing industry: A rack is an enclosed cabinet housing computer equipment. The front and back panels may be solid, perforated, or open depending on the cooling requirements of the equipment within
* Telecommunications industry: A rack is a framework consisting of two vertical posts mounted to the floor and a series of open shelves upon which electronic equipment is placed. Typically, there are no enclosed panels on any side of the rack
Frame for housing electronic equipment
Machine for imparting energy to a fluid, causing it to do work
* Centrifugal pump: Pump having a stationary element (casing) and a rotary element (impeller) fitted with vanes or blades arranged in a circular pattern around an inlet opening at the center. The casing surrounds the impeller and usually has the form of a scroll or volute
* Diaphragm pump: Type of pump in which water is drawn in and forced out of one or more chambers by a flexible diaphragm.
A graph of the properties (temperature, relative humidity, etc.) of air. It is used to determine how these properties vary as the amount of moisture (water vapor) in the air changes

Board that contains layers of circuitry used for interconnecting the other components
Globally accepted metric that is described by The Green Grid in several whitepapers. PUE illustrates the total energy used by a data center divided by the energy used by ICT equipment in that data center
