IEEE 802.3 (Institute of Electrical and Electronics Engineers standard)

IEEE 802.3 is a set of standards that governs wired Ethernet networks, facilitating the way computers and devices communicate over cables. It defines how data is transmitted, ensuring reliability, speed, and compatibility across different hardware. Originally developed in the 1980s, it has evolved to support various speeds, from 10 Mbps to 400 Gbps and more. The standard covers aspects like the physical connections, data formatting, and network protocols, making it essential for both home and enterprise networking, enabling devices to share information seamlessly and efficiently across local area networks (LANs).
