B) AGP (Accelerated Graphics Port) is a parallel expansion card standard designed specifically for attaching a video card to a computer system to assist in the acceleration of 3D computer graphics. It was first introduced in 1997 by Intel and has since become widely adopted in the industry.

AGP provides a direct connection between the video card and the system's memory, allowing for faster data transfer and improved performance in graphics-intensive applications. It offers higher bandwidth and lower latency compared to other expansion card standards such as PCI (Peripheral Component Interconnect).

AGP operates at different speeds, including AGP 1x, AGP 2x, AGP 4x, and AGP 8x. Each speed represents the maximum amount of data that can be transferred per second. The higher the speed, the faster the data transfer and the better the graphics performance.

AGP also supports features such as sideband addressing and pipelining, which further enhance its performance. Sideband addressing allows the video card to send commands and data to the system's memory independently of the main bus, reducing latency and increasing overall efficiency. Pipelining allows multiple data transfers to occur simultaneously, improving overall throughput.

One of the key advantages of AGP is its dedicated bandwidth for graphics data. Unlike other expansion card standards that share bandwidth with other devices on the system bus, AGP provides a dedicated channel for graphics data, ensuring that the video card has the necessary resources to deliver high-quality graphics in real-time.

In conclusion, AGP is a parallel expansion card standard designed specifically for attaching a video card to a computer system to accelerate 3D computer graphics. It offers higher bandwidth, lower latency, and dedicated resources for graphics data, resulting in improved performance in graphics-intensive applications.
