What type of connection allows devices in close proximity to communicate effectively?

The correct choice is Personal Area Network (PAN). A PAN is designed for short-range communication, typically covering a small area, such as a few meters. It allows devices such as smartphones, tablets, and laptops to connect and communicate with each other directly, often using wireless technologies. This type of network is particularly useful for personal devices that need to share data or resources over a limited distance.

For example, when you connect your smartphone to wireless headphones or a smartwatch, you are utilizing a PAN, as these interactions involve devices that are in close proximity to each other.

While options like Wireless Local Area Network (WLAN) and Bluetooth provide connectivity, WLAN is typically used for broader networking covering larger areas (like an entire building or campus), and Bluetooth is a technology often used within a PAN but does not define the network itself. Wide Area Networks (WAN) encompass much larger geographic areas and are not designed for close-proximity connections. Thus, recognizing the specific characteristics and intended use of a Personal Area Network helps clarify why this is the most suitable choice for short-range communication among nearby devices.
