Why is Ethernet so complex but still relevant 🌐 The evolution of ethernet cables reveals how eight copper wires and four twisted pairs became the backbone of high speed data transmission, noise reduction and differential signaling. The combination of balanced pairs, precise color coded standards and backward compatible wiring layouts such as T568A and T568B allowed networks to upgrade from 10 Mbps to 100 Mbps and 1 Gbps without replacing the physical cabling. This structured design continues to
