What is the difference between diode & cathode?

A semi-conductive diode is a basic component of a huge number of electrical systems. These components have two terminals—one that takes in electricity and one that lets it out. This process works in one way; if a terminal takes in electricity, it doesn’t let power back through. The cathode is the part of a diode that allows power to flow out, and an anode is the part that allows it to flow in. It is the combination of these two elements that allows the diode to function.

a diode is a junction formed by joining a p type semiconductor to n type semiconductor or vice versa . But a cathode is an electrode which is negatively charged and used in electrolysis
