Which device is primarily responsible for rendering images on the screen?

• A. Random Access Memory
• B. Power supply
• C. Central Processing Unit
• D. Graphics Processing Unit

Answer: (D)

Rendering images on the screen is handled primarily by the graphics processing unit. This device is built with many small cores that run graphics tasks in parallel, which is exactly what image rendering needs: transforming 3D coordinates, applying textures, shading, and converting everything into the final grid of pixels. It follows a graphics pipeline that starts with geometry data and textures, runs through vertex processing and shading, rasterization, and finally writes colors to a framebuffer that the monitor displays. The CPU can assist by preparing data or performing software rendering, but it’s not optimized for the heavy, parallel math involved in rendering. System RAM holds data the GPU and CPU use, but it isn’t responsible for rendering the image itself. The power supply simply provides power to the computer; without it, nothing runs.
