It's a graphics API. Goto http://nehe.gamedev.net and check out the tutorials to learn how to use it.

Wikipedia will give you a better answer than most people have time to write here, to be honest. http://en.wikipedia.org/wiki/Opengl

OpenGL is a 3D graphics API. It allows you to render 3D graphics etc. It is pretty much very similar to DirectX however OpenGL is cross platform, it can be on linux or windows etc. Where as DirectX is purely windows based, OpenGL stands for Open Graphics Library.

OpenGL is similar to Direct3D, not DirectX. DirectX is a kit of API's, where OpenGL is only for graphics, just as Direct3D of DirectX.

DirectX is windows/xbox based, while OpenGL is cross platform. However do not be mislead by the "Open" in OpenGL. It's not "open source" in any way.

Just clarifying what i assume GDKnight meant ;)

it can't be open source. its a specification.

there are implementations that are open source, mesa

but most implementations are interfaces to hardware drivers and are not
