👉 The Ethernet fluid, often referred to as the copper or twisted-pair medium, is a physical medium used in Ethernet networks for transmitting data. It consists of thin, insulated copper wires that carry electrical signals representing binary data. These wires are organized into pairs, typically with one pair carrying the data in opposite directions (half-duplex communication), ensuring that signals don't interfere with each other. The fluid's design, including its structure and insulation, enables efficient and reliable data transfer over short to medium distances, making it the backbone of modern local area networks (LANs).
