If you put water on the stove, the hot water at the bottom will move up - the entire pot of water will get mixed.
Conduction.
A pot of water heating on a stove.
Convection is "the transfer of heat through the motion of molecules in a fluid."
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.

Convection heat transfer is the transfer of heat by the movement of a fluid.
Conduction.
Convection oven is an example. A convector is a general name for something that transfers heat by convection.
