The Endless Evolution of Ethernet

You likely use Ethernet every day, but its design is rooted in 1970s radio technology. It cleverly mimics how people converse at a party to manage data traffic without constant collisions.

Originally inspired by a radio network in Hawaii, Ethernet uses a fascinating method called carrier sense multiple access. Computers essentially listen for silence on the wire before transmitting, much like waiting for a gap in a conversation. If two devices speak at once, they back off and retry after a random delay. This resilient design has evolved from early coaxial cables to the lightning-fast speeds we rely on today.
