Which type of network is used for short-range communications, usually within a few feet?

Rationale

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

A Personal Area Network (PAN) is designed specifically for short-range communication, typically connecting devices within a range of up to about 10 meters (33 feet). This network type is commonly used for personal devices such as smartphones, tablets, and laptops to communicate with each other wirelessly.

A (Personal area network (PAN)) CORRECT

This choice accurately describes a network type specifically tailored for short-range communications, making it the correct answer. PANs facilitate seamless interaction between personal devices in close proximity, utilizing technologies like Bluetooth and infrared.

B (Local area network (LAN)) YOUR ANSWER

A Local Area Network (LAN) covers a larger area than a PAN, typically spanning a single building or a campus. While LANs support multiple devices and services, they generally operate over distances of several hundred meters to a few kilometers, which exceeds the short-range characteristic defined in the question.

C (Extended area network (EAN)) YOUR ANSWER

An Extended Area Network (EAN) is not a standard term widely recognized in networking. However, if used, it would imply a network designed for broader coverage than a LAN, thus not fitting the short-range communication criteria specified in the question.

D (Wide area network (WAN)) YOUR ANSWER

A Wide Area Network (WAN) connects devices over large geographical distances, often across cities or countries. This network type is designed for long-range communications, which directly contradicts the short-range focus of the question.

Conclusion

In summary, a Personal Area Network (PAN) is the only type of network defined for short-range communications, typically within a few feet. Other options, such as LAN, EAN, and WAN, cater to broader distances, making them unsuitable for the context of short-range device communication. The distinction between these network types is crucial for understanding their respective use cases in personal and professional environments.

Which type of network is used for short-range communications, usually within a few feet?

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