Important Points

Conversion of electrical energy to chemical energy and vice versa is known as electrochemistry.
Based on this there are two types of cells namely: Electrolytic cell and Electrochemical cell.
A cell consists of two electrodes dipped in their respective electrolytes. Each electrode and its electrolyte acts as one half cell.
In one half cell oxidation occur and is known as Anode whereas in the other half cell reduction occurs and is known as Cathode.
The two electrolytes are connected by a salt bridge or a porous pot. This whole assembly is known as Galvanic Cell or Voltaic cell.
