Graphics Architecture refers to the design and organization of hardware and software components that work together to render images and graphics on a computer. It includes the Graphics Processing Unit (GPU), which performs complex calculations to create visuals, and the Graphics API that allows software to communicate with the hardware. This architecture is essential for applications like video games, simulations, and graphic design, where high-quality visuals are crucial. By optimizing how data is processed and displayed, Graphics Architecture enhances performance and efficiency, enabling smoother graphics and more immersive experiences for users.
