A graphics card, also known as a video card, display card, or video adapter, is an expansion card that generates a feed of output images to a display device (such as a computer monitor). It is one of the most essential components of a computer system, as it is responsible for rendering images, videos, and other visual content.
Graphics cards are used in a wide variety of applications, including gaming, video editing, and computer-aided design (CAD). In recent years, graphics cards have become increasingly important for gaming, as they are responsible for rendering the 3D graphics that are used in most modern games.
