A "videokártya," or graphics card, is a crucial component in computers that processes and renders images, videos, and animations. It enhances the visual output by offloading these tasks from the central processing unit (CPU), allowing for smoother graphics and better performance in applications like video games and graphic design software. Modern videokártyák come with their own memory, known as VRAM, which helps store textures and images for quick access. They connect to the motherboard via a PCIe slot and can support multiple displays, making them essential for gamers, designers, and anyone who requires high-quality visual performance.
