A wearable activity tracker measuring steps and heart rate is a fitness or wearable device, not an example of WiMAX, which is a wireless broadband technology.

A collection of nodes doing environmental sensing, local computation and peer communication is a wireless sensor network, not a Geographic Information System.

Only the first description of these information-technology trends holds true.

Qubits exploit superposition to represent more than a single binary state at once.

A Geographic Information System instead stores and analyses spatial and geographic data.
