Drag and drop
Copying, moving and linking function, used at graphics user interfaces. Objects are selected with the mouse,
held and moved from one data area to another.
Earth
The conductive earth whose electric potential can be set equal to zero at every point. In the area of earth elec-
trodes the earth can have a potential deviating from zero. The term "Earth reference plane" is often used for
this state.
Earth (verb)
This term means that a conductive part is connected via an earthing system to the → earth.
Earthing
Earthing is the total of all means and measures used for earthing.
