Rendering Definition
Rendering is the process of generating a final digital product from a specific type of input. The term usually applies to graphics and video, but it can refer to audio as well.
1. Graphics
3D graphics are rendered from basic three-dimensional models called wireframes. A wireframe defines the shape of the model, but nothing else. The rendering process adds surfaces, textures, and lighting to the model, giving it a realistic appearance. For example, a 3D drawing applica...

OpenGL Definition
OpenGL, or the Open Graphics Library, is a 3D graphics language developed by Silicon Graphics. Before OpenGL was available, software developers had to write unique 3D graphics code for each operating system platform as well as different graphics hardware. However, with OpenGL, developers can create graphics and special effects that will appear nearly identical on any operating system and any hardware that supports OpenGL. This makes it much easier for developers of 3D game...

GPU Definition
Stands for "Graphics Processing Unit." A GPU is a processor designed to handle graphics operations. This includes both 2D and 3D calculations, though GPUs primarily excel at rendering 3D graphics.
History
Early PCs did not include GPUs, which meant the CPU had to handle all standard calculations and graphics operations. As software demands increased and graphics became more important (especially in video games), a need arose for a separate processor to render graphics. On A...
