Solution

  +-------+       +--------------+       +----------+       +----------+       +---------+
  |  CPU  | ----> | Vertex       | ----> | Shading  | ----> | Frame    | ----> | Display |
  |       |       | Processing   |       | Processing|       | Buffer   |       | Screen  |
  +-------+       +--------------+       +----------+       +----------+       +---------+

Explanation:
1. The CPU sends graphics data to the GPU.
2. The GPU processes vertices, which are points defining shapes.
3. Shading adds colors, textures, and lighting effects to pixels.
4. The processed image is stored in the frame buffer.
5. Finally, the frame buffer sends the image to the display screen for viewing.

This diagram shows the main steps of graphics processing by a GPU:

CPU: The central processor sends raw graphics data to the GPU.
Vertex Processing: The GPU breaks down the data into vertices, which define the shapes and positions of objects.
Shading Processing: The GPU applies colors, textures, and lighting to pixels, making the image look realistic.
Frame Buffer: The fully processed image is stored temporarily here.
Display Screen: The final image is sent to the screen so you can see it.

This flow shows how the GPU helps create images quickly and smoothly, making games and videos look good.
