Which of the following computing devices is MOST likely to have an internal wireless antenna?

Mobile phones are inherently designed for wireless communication, relying heavily on cellular, Wi-Fi, and Bluetooth technologies for their core functionality. Therefore, they always include multiple internal wireless antennas optimized for various frequency bands to ensure connectivity without external components.

While many modern workstations (desktops and laptops) do include internal wireless antennas for Wi-Fi and Bluetooth, it is not a universal or primary defining feature for all workstations, especially older desktop models which might rely on wired connections.

Servers are typically designed for high reliability and performance in data centers and primarily rely on wired Ethernet connections for network access; wireless connectivity is rarely a standard, internal feature.

Network Attached Storage (NAS) devices are primarily designed for network-based file storage and access, almost exclusively using wired Ethernet connections for stability and bandwidth, and typically do not include internal wireless antennas.
