Accelerated Graphics Port (AGP) is a type of connection interface that is used for high-speed communication between a computer's central processing unit and its graphics card. The AGP was first introduced in 1996 to enhance 3D gaming and video performance. Some commonly used synonyms for AGP include Graphic Accelerator Port, Advanced Graphics Port, and High-Speed Graphics Port. AGP has evolved since its inception, with newer versions such as AGP 2.0, AGP Pro, and AGP 3.0. While AGP has been mostly replaced by newer technology such as PCI Express, it is still used in some older systems and remains an important part of computer history and development.
