Difference between Cathodic and Galvanic Protection

[fishbiscuit]

Is there a difference in the first place? This is my understanding of it: (i'm asking this question to just clarify my understanding is correct)

I'm using the Jacaranda HSC textbook and they define galvanic protection as:
"Iron and steel can be prevented from rusting by making them cathodic in a galvanic cell"

and then they define cathodic protection as:
"an electrochemical method used to protect metals from corrosion by making them the cathode (reduction electrode) in a galvanic cell."

And then they say:
 "...steel structures in wet terrestrial or coastal environments can be protected from rusting by establishing an electrolytic cell in which the steel is the cathode. This process is called applied voltage, impressed current or active cathodic protection."

So, what I got from that is;
Cathodic protection = galvanic protection = galvanic cell
Active cathodic protection = electrolytic cell

So is galvanic protection the same thing as cathodic protection? Or am i missing something?
