36. Which type of network is used for short-range communications, usually within a few feet?
Answer: D
Personal area network (PAN) is used for short-range communications, usually within a few feet.
A personal area network (PAN) is designed for short-range communication, typically covering a few feet, making it ideal for connecting devices such as smartphones, tablets, and laptops in close proximity.
A) Wide area network (WAN)
A wide area network (WAN) spans large geographical areas, often connecting multiple cities or countries. It is not suitable for short-range communications, as its purpose is to facilitate long-distance connections.
B) Extended area network (EAN)
An extended area network (EAN) is not a standard network type widely recognized in networking terminology. Therefore, it cannot be considered correct for short-range communication, as it lacks a defined purpose or application related to that context.
C) Local area network (LAN)
A local area network (LAN) typically covers a larger area than a PAN, such as a home, office, or building. While a LAN can support short-range communications, it is not limited to just a few feet, making it less appropriate for the question's specific criteria.
D) Personal area network (PAN)
A personal area network (PAN) is specifically designed for short-range communication, typically within a range of a few feet. This makes it the most appropriate choice for connecting personal devices in close proximity.
Conclusion
The correct answer, personal area network (PAN), is specifically tailored for short-range communications, aligning perfectly with the question's requirement. All other options, including WAN, EAN, and LAN, either cover larger areas or do not fit the context of short-range communication, reinforcing that PAN is the definitive correct response.
