A support level is the price level that an asset doesn't fall below for a period of time. An asset's support level is created by buyers entering the market whenever the asset dips to a lower price.

The simple support level can be charted in technical analysis by drawing a line along the lowest lows for the period being considered. The support line can be flat or slanted up or down with the overall price trend. Other technical indicators and charting techniques can be used to identify more advanced versions of support.
