Ethernet
Network transmission system that was developed and standardised by DED, Intel and Xerox and is characterised by the following components: baseband technology, CSMA/CD access method, variable packet length from 64 to 1518 bytes, transmission rate of 10 Mbit/s, logical bus topology, coaxial cable. The subsequent IEEE 802.3 standard has ensured integration into the ISO/OSI reference model since 1983 and extends the physical layer and transmission media to include repeaters and implementations based on fibre optics, broadband and twisted pair. The protocols of layers 3 and 4 are also frequently included. The term Ethernet is often used as a general term without distinguishing between the different transmission rates of 10 Mbit/s, 100 Mbit/s (-"Fast Ethernet), 1000 Mbit/s (Gigabit Ethernet).
