A graphics card is a computer component that contains a processing unit (GPU), cooling system, and output interface. It is designed to process visual data and convert it into a format that can be displayed on monitors.
Processing visual data is resource-intensive, and adding a graphics card with dedicated memory into an expansion slot on the computer's motherboard can improve its performance significantly. Built-in graphic cards are less efficient because they share available memory with the system's CPU.
Graphic cards are primarily used to render images, videos, and animations and are indispensable in the gaming, video editing, and 3D modeling industries.
