IEEE 802.3i, 3u, 3ab, 3x

What is IEEE 802.3i, 3u, 3ab, 3x?

IEEE 802.3 is a set of Ethernet standards that define the physical and data link layers of wired Ethernet networks.

Some of the most commonly used Ethernet standards include IEEE 802.3i, 3u, 3ab, and 3x. IEEE 802.3i, also known as 10BASE-T, is the original Ethernet standard that specifies a data transfer rate of 10 megabits per second (Mbps) over twisted pair copper cables. It uses a star topology and supports a maximum cable length of 100 meters. IEEE 802.3u, also known as 100BASE-TX, is a faster Ethernet standard that specifies a data transfer rate of 100 Mbps over twisted pair copper cables. It uses the same star topology as 10BASE-T and supports a maximum cable length of 100 meters. IEEE 802.3ab, also known as 1000BASE-T, is a gigabit Ethernet standard that specifies a data transfer rate of 1 gigabit per second (Gbps) over twisted pair copper cables. It uses a four-pair cabling system and supports a maximum cable length of 100 meters. IEEE 802.3x is a flow control standard that defines a mechanism for managing the flow of data between devices on an Ethernet network. It is used to prevent network congestion and data loss by allowing devices to pause data transmission when the receiving device is busy. These Ethernet standards are widely used in various network environments and provide a framework for building reliable and high-performance Ethernet networks.
