Ground (sometimes called neutral or earth) is usually at 0V. Ground acts a reference point for most electronic circuits. It is good practice to connect all ground references to a common point; inversely, it is a very bad practice to leave floating ground points in your circuit. This is important if you are using multiple benchtop instruments simultaneously. For example, the function generator and the oscilloscope should be connected to a common ground in your circuit so that they can produce and display waveforms accurately.
