What is primarily housed on the motherboard with regard to video display?

The graphics card, also known as a video card or GPU (Graphics Processing Unit), is primarily housed on the motherboard because it is responsible for rendering images, video, and animations, and facilitating the display output of a computer. The motherboard provides the necessary connections and communicates with the CPU and memory to process graphical data, ensuring that the system can display graphics-rich applications effectively.

In modern computers, the graphics card can be integrated directly into the motherboard (using onboard graphics) or installed as a separate component in a dedicated slot. This integration helps optimize space and resources, allowing for better performance in tasks such as gaming, video editing, and graphic design.

While RAM is also located on the motherboard, it specifically stores temporary data that the CPU needs for processing, not directly related to the video output. The cooling system is essential for maintaining optimal temperature levels for various components but is not primarily associated with video display functions. The power supply is a separate entity that provides electrical power to the computer's components, including the motherboard and graphics card, but does not interact with video display directly.
