IEEE 802.3u

IEEE 802.3u is a standard that defines how fast Ethernet networks operate, specifically focusing on 100 Mbps speeds, known as Fast Ethernet. It describes how devices like computers and switches connect using Ethernet cables to transfer data quickly and reliably over local area networks (LANs). The standard specifies the wiring, signal timing, and protocols so devices can communicate seamlessly. Essentially, 802.3u enables faster and more efficient network connections in homes and offices, improving overall data transfer rates while maintaining compatibility with existing Ethernet technology.
