**802.3**

What is 802.3?

IEEE 802.3 is a collection of IEEE standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. It is commonly used to implement local area networks (LANs) with various speeds, such as 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T (Gigabit Ethernet), and 10GBASE-T (10 Gigabit Ethernet). It defines how data is transmitted over wired connections using Carrier Sense Multiple Access with Collision Detection (CSMA/CD).
