A diode is an electrical check valve. This assumes you know what a check valve is.
An alternator is a poly phase generator. The World operates on 3-phase power. Automotive alternators have more than 3-phases, i.e. poly phase. The diodes convert the AC to DC with a lot of ripple. The battery smooths out the ripple. Never run the engine without a battery. Electronics don't like AC ripple.
3G has 4 diodes.
