A computer graphics card, also known as a graphics card, is the device responsible for generating images on a computer screen. Its main function is to process and send graphics to the screen, making it a key component in processing visual information.

The graphics processing unit (GPU), which is specifically designed to perform graphics tasks quickly, plays a key role in the display driver. It also contains its own memory, GDDR memory, dedicated to graphics tasks and enhances the processing of image data. A graphics card often has multiple display outputs, such as HDMI, DisplayPort and DVI, allowing multiple displays to be used simultaneously. The performance of graphics cards ranges from simpler models suitable for basic use and gaming to more powerful models needed for heavy graphics applications and 3D gaming. Some computers use an integrated graphics card, while others use a separate graphics card that can be replaced or added as required. Modern graphics cards support advanced graphics technologies such as ray tracing and offer support for virtual reality (VR). Two major manufacturers of graphics cards are NVIDIA and AMD, which offer a wide range of different models to meet the needs and budgets of different users. The choice of graphics card depends on the user's needs, and it is important to ensure compatibility with other computer components and the display being used.
