Q2) Describe the Near Field Communication (NFC) technology.
Answer: Near Field Communication (NFC) is a wireless technology that establishes a communication link between two NFC devices that are within 4 inches of each other. For example, when you tap your smart phone with that of your friend, the two phones can use NFC to exchange contact information. NFC can also be used to read an NFC tag, which is a small microchip that can be embedded in just about anything, including a key chain tag, printed flyer, or billboard. The NFC tag dispenses information to any NFC-enabled smart phone or other device that comes within 4 inches of the tag.
Q3) Hard drives have three connections for cables: one for reading data, one for writing data, and one for power.

Q2) Describe the PCI Express bus and contrast it with previous versions of the PCI bus. Answer: PCI Express (PCIe) uses an altogether different architectural design than conventional PCI and PCI-X; PCIe is not backward compatible with either. PCI Express will ultimately replace both these buses as well as the AGP bus, although it is expected PCI Express will coexist with conventional PCI for some time to come. Whereas PCI uses a 32-bit or 64-bit parallel bus, PCI Express uses a serial bus, which is faster than a parallel bus because it transmits data in packets similar to how an Ethernet network, USB, and FireWire transmit data. A PCIe expansion slot can provide one or more of these serial lanes. Another difference in PCI Express is how it connects to the processor. One or more PCI Express slots used for video cards have a direct link to the North Bridge or to the processor (using Sandy Bridge or Ivy Bridge architecture). PCI Express currently comes in four different slot sizes called PCI Express ×1, ×4, ×8, and ×16.
