As many professionals in the communications technology field will agree, the ethernet network is like a pair of jeans. The design has existed for years and although there have been several improvements over time; the essential concept remains the same. Unlike looking into your wardrobe of boyfriend jeans, dark denim, and flares however, looking at the evolution of the ethernet network is not quite as apparent.
Robert Metcalfe at Xerox PARC originally invented the ethernet network in 1973-74. However, there has been some contention over this since it wasn't until 1975 that a patent was filed and the network system wasn't used at PARC until 1976.
Robert worked as a researcher at Xerox's Palo Alto Research Centre and was responsible for creating a network system for Xerox's new computers and laser jet printer. The original ethernet network simply allowed computers to transmit data packets with one another using a shared coaxial cable. This enabled the computers to find one another with 48-bit destination and source addresses. The original ethernet network could transfer 10 million bits per second and in order to navigate and identify the appropriate sources to deliver data packets it used a 16-bit Ethertype type field.
Metcalfe released ethernet network onto the consumer market in the 1980s, when Token Ring and Token Bus were its biggest competitors. However the ethernet network's switch from a coaxial cable to twisted pair wiring in the early 90s gave it dominance over the market.
The coaxial cable worked fine initially. However the growing popularity of ethernet networks and the demands of media content meant that industry professionals were forced to alter the technology. The original cable was simply too small to cope with large extended networks. This mean that collisions, where data packets collide with one another, were a frequent occurrence and eventually this resulted in many transmitted information being lost. In the early 90s, the thick cable of the ethernet network was replaced by a much smaller thinner cable intended to reduce costs and make installation easier.
