What is the primary function of the video card in a computer?

• A. Store memory
• B. Decode audio
• C. Process network traffic
• D. Render graphics

Answer: (D)

Rendering graphics is the primary job of the video card. The GPU specialized on drawing images uses textures, shading, and lighting to turn data into the pixels you see on the screen. It has its own memory (VRAM) to store textures and the frame buffer, and it outputs the video signal to the monitor, taking much of the graphical workload off the CPU so visuals appear smooth and responsive. The other options aren’t the main purpose: storing memory isn’t what the video card is designed to do (that's RAM and storage), decoding audio is handled by audio hardware, and processing network traffic is the job of network components. Rendering graphics is the function that directly creates what you view.
