Question

You are a consultant for a small to mid-range business and have been hired to evaluate your customer’s server hardware. You notice that all of their hardware currently uses the PCI bus, and you recommend that they upgrade to PCI Express (PCIe) equipment. What is the reason for your recommendation?

A. PCI-standard hardware has a number of flaws that can be used by hackers on the Internet to compromise the security of server data.

B. PCI standard hardware is old and slows down the performance of servers compared to the newer, faster PCIe standard.

C. PCI standard hardware cannot support USB data transfers, which are becoming increasingly more important in the modern work environment.

D. PCI standard hardware tends to increase the heat output of servers, leading to premature aging of hardware and possible data damage.

Answer 1

PCI - Perpheral Component Interconnect

PCI-E is improved version of PCI and which is more faster than PCI.

PCI uses parallel interface where as PCI-E uses serial interface.

PCI uses shared bus where as PCI-E uses specialised buses for every device connected to it.

PCI runs at 133Mb/s where as PCI-E runs at 16GB/s

So,Option B is right description
