Which of the following is considered a Personal Area Network (PAN)?

A Personal Area Network (PAN) is defined as a small, localized network, typically used for connecting personal devices within a limited range, often a few meters. It facilitates communication between personal devices such as smartphones, tablets, laptops, and other peripherals like printers and smartwatches within a close proximity.

The workspace setup of an individual can encompass various personal devices connected through Bluetooth or Wi-Fi, thereby forming a personal area network. This setup allows the individual to easily share files, synchronize data, and utilize devices without needing an expansive network infrastructure.

In contrast, a corporate office network is designed for larger, multi-user environments, typically serving an entire organization rather than just individual connections. A city-wide Wi-Fi service covers a broad geographic area, connecting many users over a wide range, which doesn't fit the PAN definition. A data center network is focused on data management and storage, involving vast numbers of servers and equipment, which are not personal devices and thus do not align with the concept of a PAN.

This makes the individual’s workspace setup a prime example of a Personal Area Network, emphasizing the personal, localized nature of the devices involved.
