Adapter cards allow computers to connect to external devices and expand their functionality. There are several types of adapter cards including video cards for displaying graphics, multimedia cards for audio/video, I/O cards for connecting devices like scanners and printers, and communication cards for networking. Key interface types are PCI, AGP, and PCI-E, with AGP specifically designed for video cards and PCI-E using a newer architecture than PCI.

8. AGP

9. AGPThis interface was developed specifically to connect with the video card, by opening a direct memory access (DMA) channel to the graphics board.

10. It is 32 bit bus.

11. Cards which employ this bus require less on-board memory; because they can directly access graphical data stored in central memory, their cost is hypothetically lower.

12. Almost always called AGP (Accelerated Graphic Port). But in newer motherboard you will find PCI-E.AGP card

13. PCI-EPCI Express uses an entirely different architecture, different slot sizes, and is incompatible with with PCI or PCI-X. It’s expected to coexist with PCI-X and not replace it.
