ground - Computer Definition
A conducting connection, whether intentional or accidental, by which an electric circuit is connected at some point to the earth, or to some other large conducting body that can serve in place of the earth. The point can be a single point common to a great many circuits, such as an equipment frame, chassis, or cabinet. A ground serves as a reference point, a return path for an electrical signal, and to carry current safely away from a circuit in the event of a fault. In the event that earth is not available as a ground, the conducting frame of an aircraft, spacecraft, or land vehicle not conductively connected to the earth can serve as ground. See also circuit, current, electricity, and signal.
A reference voltage level of "zero potential" for electric and electronic circuits. For most equipment plugged into an AC outlet, the word ground generally refers to the earth, and the metal parts are grounded ("chassis ground") to the earth for safety. In the case of a short circuit, the current flows through the green wire and third prong in the power cord (U.S. and Canada), which causes the circuit breaker to trip. Signal Ground Power supplies, circuit boards and signal pathways in most electronic equipment are also connected to the same earth ground as the chassis for reference voltage and safety. There are exceptions; for example, medical equipment that is attached to a patient is generally isolated from earth ground even when plugged in, because the time between a short circuit and the breaker tripping could prove fatal. Ethernet adapters and other networking equipment are also isolated from earth ground in order to prevent unbalanced ground loops from causing interference (see ground loop). Portable Devices Every portable, battery-operated device, such as a laptop and iPod, as well as the electrical systems in every vehicle, have their own zero reference voltage. Naturally, these systems are not connected to earth ground, but the reference voltage is still called ground. Building Grounds At the electric panel in U.S. and Canadian buildings, the ground lines are wired to the neutral line of the electric service, to the earth via a ground rod and to the metal plumbing pipes. In large datacenters, a separate ground system may connect every server via heavy-duty cable to the metal structure of the building to ensure that the voltage reference between all equipment is the same. See ground loop.

ground - Science Definition
- A connection between an electrical conductor and the Earth. Grounds are used to establish a common zero-voltage reference for electric devices in order to prevent potentially dangerous voltages from arising between them and other objects. Also called earth.
- The set of shared points in an electrical circuit at which the measured voltage is taken to be zero. The ground is usually connected directly to the power supply and acts as a common “sink” for current flowing through the components in the circuit.
