Applying A Texture To A Single Face?

How do I apply a texture to a single face of a cube? I’m fairly new to blender, so I’m not really sure what I’m doing a lot of the time.
Note: I’m using blender 2.56

i checked out blender website, and got to this…

Jonathon Williamson has a lot of good tutorials

just give that face a new material and add a texture for that material, for the mapping you can use generated, you’ll have to check the axis of projection. you have to be in edit mode to assign materials to specific faces. or uv map it, but if it’s just a face on a cube, first way is just easier.
