A video card, also known as a graphics card, is an essential component of a computer that processes and renders images, animations, and videos. It enhances the visual experience by offloading graphics processing from the CPU, allowing for smoother gameplay and better performance in graphic-intensive applications. Modern video cards come equipped with their own memory, known as VRAM, which helps in storing textures and images for quick access. Video cards are particularly important for gamers and professionals in fields like graphic design and video editing. They come in various models and specifications, catering to different performance needs and budgets. Popular brands include NVIDIA and AMD, which offer a range of options from entry-level to high-end models suitable for demanding tasks.
