WiFi
WiFi operates at genuinely impressive velocities, with modern WiFi 6E standards capable of theoretical speeds exceeding 9.6 gigabits per second. This allows for the transmission of entire films in seconds, real-time video communication across continents, and the instantaneous delivery of memes to millions. The electromagnetic waves carrying WiFi signals travel at the speed of light, approximately 299,792 kilometres per second through vacuum (slightly slower through walls and, inexplicably, through your grandmother's house). This velocity represents one of humanity's greatest technological achievements, enabling global commerce, communication, and the regrettable rise of the instant reply. From the moment you request a webpage to its appearance, mere milliseconds elapse in a dance of photons and electrons.
