It depends on the car.
Some cars (mostly cheaper cars e.g. current Fiesta) use a single headlamp each side, with a twin-filament bulb. There is a shield around the bulb within the headlamp that block part of the beam when the dipped-beam filament is used, but doesn't block the main beam filament (due to the relative positions of the two filaments. With this system, to prevent the bulb overheating, only one filament is used at a time, which means there is a very slight dark period (a fraction of a second) when switching from one beam to the other.
Many modern cars (e.g. current Golf) use two separate bulbs each side, one for dipped beam and one for main beam, each within their own reflector. In this case, only the bulb for the dipped-beam lamp has a shield around it (or in front of it if a projector-type lens is used for the dipped-beam unit). With this system, the dipped beam remains lit when the main beam is turned on.
Some cars (e.g. Lamborghini Gallardo, or a new Zafira with optional xenon lamps) use a single bulb each side within a projector unit, but with a moveable rather than fixed shield to provide the dipped beam. With this system the bulb remains on when switching between beams, but the shield that provides the dipped-beam moves out of the way, allowing all light to reach the projector lens, to provide the main beam.

Depending on weither the car has 2 or 4 headlights. The 2 lamp system has 2 elements in the bulb and the 4 lamp system has one in each bulb. On the older cars both the low and high beams worked together, so all 4 lights came on when you applyed the high beams. On the newer cars with 4 lamps when you apply the high beams the low beams cut off and the same when you apply the low beams. The high beams cut off.

It is one bulb with 2 filaments, 1 for main beam and 1 for dipped headlights.

You mean high beam and low beam? Depends on the car, look at the headlights... if there are two (one on each side) low and high are combined. But if there are 4 (two on each side) then the inner pair are the high beams AND the outer pair are "combined" beams. So, on low beam the outer pair are on and the inner ones are dark, on high beam all four are on high. Suggestion... turn the lights on and get out and look! First on low, then on high.

there are no difference, they are both the same, 12v 45 watt, the only difference maybe the connectors on the bulb, IE 1, 2, or 3 pin, but the general is no difference
