Ethernet
History and Standardization of Ethernet:
Ethernet was developed at Xerox PARC between 1973 and 1974, inspired by ALOHAnet studied by Robert Metcalfe. The IEEE 802.3 standard was published in 1983, establishing Ethernet as the dominant networking technology by the late 1980s. The standardization process began with the IEEE project 802 in February 1980, with the DIX-group submitting the Blue Book CSMA/CD as a LAN standard candidate, supported by Siemens for international standardization in 1981.
Evolution and Adoption of Ethernet:
Over the years, Ethernet data rates have increased significantly, from 2.94Mbit/s to 400Gbit/s. Modern Ethernet predominantly uses twisted pair and fiber optic links, with 3Com shipping the first 10Mbit/s Ethernet NIC in 1981. Ethernet gained popularity for PC networking in the 1980s and is now widely used in homes, industries, and integrated with Wi-Fi technology.
Market Impact and Varieties of Ethernet:
The Ethernet equipment market surpassed $16 billion annually by 2010, and Ethernet is now used to interconnect various appliances and personal devices. Ethernet’s physical layer encompasses coaxial, twisted pair, and fiber-optic interfaces, supporting speeds ranging from 1 Mbit/s to 400 Gbit/s. The evolution of Ethernet’s physical layer has seen the incorporation of different media interfaces and speeds to meet diverse networking needs.
