The term Ethernet names the technological standard used by physical communication networks. It comes from the word ether, the physical concept that became popular in the 19th century: a fluid believed to fill all space and to carry the propagation of light. Quite naturally, the term was chosen to name a kind of invisible network we use to communicate.

«Ethernet», the network that was always there, an invisible and ever-present fabric. An ether imagined and made real despite never having existed.
