what is a localizer?

any time I fly IFR, I'm told to wait for the localizer before coming into land. I'm sure this is a basic question along the lines of how do you breathe, but I have no idea what it is.

The Localizer is a radio navigation aid used to help aircraft align with the runway during an instrument approach in low visibility. Can be used alone such as during a localizer approach or in conjunction with the a Glideslope signal thus making up the ILS or Instrument Landing System. Only some runways have this aid, click on the airport symbol in MAP mode to see if available and to determine the frequency for the Localizer.

thanks for that - I was a little confused. Now I know what the app button is for as well.
