Most likely is that one or both of the bulbs have failed. Many cars use separate bulbs for low beam and high beam, so one set failing will not stop the other.
Once you have replaced the bulbs, if they are still not working check:
Fuses
Wiring, especially the earth connection at the bulb holder
Switch

No the high beam filament is independent from the low beam filament You can run them seperately or together . it depends on how the lights are set up. For instance if you have your high beam on you may have your lows running at the same time, however if your low beam is on low beam setting, your highs are always turned of It sounds like you may need to look at your fuses or your switch.
