What is cathodic and anodic protection for controlling corrosion?

Herein, what is cathodic and anodic protection?
Cathodic protection converts all anodic areas on a metal surface to cathodes so that corrosion ceases. Anodic protection, on the contrary, makes the entire metal surface an- odic-so anodic that the metal completely passivates.
Secondly, which is better anodic coating and cathodic coating? Tin coated containers and utensils can be used for storing any food stuff as tin is non-toxic and protects metal from corrosion. Tinning is cathodic coating whereas Galvanizing is anodic coating so cathodic coating is preferred over anodic coating for manufacturing of containers to store food stuff.
In this regard, what is the difference between anodic and cathodic protection?
The key difference between anodic and cathodic protection is that in anodic protection, the surface to be protected acts as the anode whereas, in cathodic protection, the surface to be protected acts as the cathode. In this process, this sacrificial metal corrodes while avoiding the corrosion of the cathode.
What does cathodic protection mean?
Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.
