Ethernet is a computer network topology specified as IEEE 802.3 standard. The original Ethernet carries frame based traffic at a speed of 10 Mbit/s, yet today it is common to see Fast Ethernet which operates at 100 Mbit/s Ethernet, and Gigabit Ethernet (1000 Mbit/s) is getting traction, too
Ethernet supports a number of different cables such as twisted copper wire as well as optic fibers for example. The three most common norms are 10Base-T (original), 100Base-TX (fast), and 1000Base-T (Gigabit) using Category 5 cables and 8P8C modular connectors (depicted).
Read on to find everything you want to know about Ethernet including half-duplex, full-duplex Ethernet, 10Base-X, 100Base-X as well as 1000Base-X.
