Ground
The common point in electrical/electronic circuits. All electrons flow toward the path of least potential difference. A properly grounded system will cause errant current to flow into the
ground thereby not damaging people or equipment. When working with
electronics, ground may be abbreviated as GND and have a symbol that resembles
a down arrow, like the one shown to the right.
When working inside a computer or other electrical equipment it is important that you ground yourself first
to prevent ElectroStatic Discharge.
