Question 62

Personal area network (PAN) is used for short-range communications, usually within a few feet.

A personal area network (PAN) is specifically designed for short-range communication, typically within a range of a few feet, making it ideal for connecting devices such as smartphones, tablets, and laptops in close proximity.

A) Personal area network (PAN)

This option is correct because a personal area network (PAN) is specifically tailored for short-range communication between devices. It encompasses technologies like Bluetooth and infrared, which facilitate the connection of devices within a limited distance, typically around 10 meters or less.

B) Local area network (LAN)

A local area network (LAN) is not the correct answer as it covers a broader range than PAN, typically spanning from a few meters to several kilometers within a building or campus. LANs connect multiple devices and can support numerous users over a larger area, unlike the more restricted range of a PAN.

C) Extended area network (EAN)

This option is incorrect as an extended area network (EAN) is not a commonly recognized network type and does not specifically refer to short-range communications. The term is generally not used in networking literature, which makes it irrelevant in this context.

D) Wide area network (WAN)

A wide area network (WAN) is also incorrect because it operates over large geographical distances, connecting multiple local area networks (LANs) or other networks. WANs can span cities, countries, or even continents, making them unsuitable for short-range communications.

Conclusion

The correct answer is personal area network (PAN) as it is specifically designed for short-range communications, typically within a few feet. All other options represent networks that operate over larger distances, making them inappropriate for the defined context of short-range communication.
