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.

Solution

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

Explanation:

PCI express (PCI-E or PCIe) is an improved version of PCI that doubles and expands on data transfer rates. PCI is the standard connection interface for connecting the PC motherboard to computer peripherals that extend the computer\'s capabilities.
1.   PCIe is much faster compared to PCI.
2.   PCIe uses a serial interface while PCI uses a parallel interface.
3.   PCIe speed is classified into lanes, each capable of delivering up to 1GB/s data transfer.
4.   PCI slots are standardized while PCIe slots vary depending on the number of lanes the slot is intended for.
5.   Despite PCIe superiority, most manufacturers still use the PCI standard for their devices.
