The D stands for drive. The numbers are the highest gear that setting will let the transmission go to.

'May be overdrive or 4th gear depending on how many gears your automatic transmission has. If it's a 3 speed auto, then D4 is overdrive for highway cruising. If it's a 4 speed (or more) auto, then D$ is just 4th gear (just like a manual transmission).

D3 is drive - for everyday, around town driving. D4 is overdrive - for the open road, expressway, etc. Think of it as 3rd and 4th gear.

Depending on the context, they prevent the car from moving into higher gears. The reason you might decide to use them is when you are pulling a trailor or going up a steep incline. You don't want the transmission to constantly change gears trying to adjust to the increased strain.
