True galvanic isolation is just that - true isolation, where there is no
direct electric (galvanic) connection between the two devices. Done
using isolation transformers or optoelectrics - either an optocoupler or
a fibre connection.
The best example is ethernet using twisted pair (cat5, cat6 or whatever)
network cabling, where the ethernet interface contains tiny transformers
("magnetics") for the signal pairs.
