Your customer has asked you to describe which sort of video

Your customer has asked you to describe which sort of video adapter card would be best for a modern computer system, PCI, PCI Express (PCIe), or AGP. What do you tell her?

A. You tell her that PCI, PCIe, and AGP are all proprietary formats used by different video card makers and that there is no significant performance differences between them in modern computers.

B. You tell her that PCI and PCIe are different versions of the same adapter format, but that AGP should always be used for video cards in modern computers.

C. You tell her that PCI and AGP are older adapter standards and that PCIe is faster and preferred in modern computers.

D. You tell her that PCIe is only used for sound cards, and PCI is only used for devices like NIC cards and modems. AGP is used exclusively for video cards in modern computer systems.

Solution

ans) C , i.e.I\'\'ll tell her that PCI and AGP are older adapter standards and that PCIe is faster and preferred in modern computers.

1) Because PCIe has faster refresh rates. It’s up to 5.8 MP grayscale at full refresh rate.

2) Because PCIe provides lower latency and higher data transfer rates than parallel busses such as PCI and AGP. Every device that\'s connected to a motherboard with a PCIe link has its own dedicated point-to-point connection. This means that devices are not competing for bandwidth because they are not sharing the same bus.

3)Because With PCIe, data is transferred over two signal pairs: two wires for transmitting and two wires for receiving. Each set of signal pairs is called a \"lane,\" and each lane is capable of sending and receiving eight-bit data packets simultaneously between two points.

4) Because PCIe can scale from one to 32 separate lanes; it is usually deployed with 1, 4, 8, 12, 16 or 32 lanes. The lane count of a PCIe card is a determining factor in its performance and therefore in its price. For example, ann inexpensive PCIe device like a NICs might only use four lanes (PCIe x4). By comparison, a high-performance graphics adapter that uses 32 lanes (PCIe x32) for top-speed transmission would be more expensive
