OpenGL stands for Open Graphics Library and it is used for developing applications that draw/display graphics. It is to make it easier for developers to develop 3d applications (games) without having to write the mathematically-intense graphics functions themselves. To learn more about OpenGL, there are a number of tutorials scattered around the web and you can visit the OpenGL website at www.opengl.org

OpenGL is a graphics application programming interface (API). It allows you to draw 3D graphics from a software program and exploit the hardware acceleration of a graphics card. It is portable but you need to understand 3D graphics and some math to develop with it because it is a reasonably low level graphics API. You don't need to implement very low level functionality like trinagle rasterization.
