A closer look
Because running copper telephone wires between volcanoes is a logistical nightmare, researchers at the University of Hawaii in 1971 just built a radio-based computer network instead. ALOHAnet introduced the wildly chaotic concept of random-access packet switching—essentially letting computers scream data into the void whenever they felt like it, and only re-sending if packets collided. It sounds incredibly reckless, but this exact 'yell and hope for the best' methodology became the foundational blueprint for Ethernet and modern Wi-Fi.
