To many professionals in the communications industry, an ethernet network is like a pair of jeans. The classic design has existed for years and essentially the concept remains the same, although over the years there have been several improvements. While a quick look in your wardrobe at boyfriend jeans, flares, and dark denim may show that the changes with jeans are apparent, the evolution of the ethernet network is not quite as so.
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.
Working as a researcher at Xerox's Palo Alto Research Centre, Robert was responsible for creating a network system for Xerox's new computers and laser jet printer. His original ethernet network allowed computers to transmit data packets with one another using a shared coaxial cable, and enabled the computers to find one another with 48-bit destination and source addresses. It could transfer 10 million bits per second and used a 16-bit Ethertype type field to help navigate and identify the appropriate sources to deliver data packets.
The ethernet network was released onto the consumer market in the 1980s, at this time Token Ring and Token Bus were it's biggest competitors. However, the ethernet network was able to gain dominance over the market in the early 90s when it switched from a coaxial cable to twisted pair wiring.
The coaxial cable was initially fine, but the growing popularity of ethernet networks and the demands of media content meant that industry professionals needed to alter the technology. Collisions, where data packets collide with one another, happened frequently and this lead to a lost in transmitted information. The reason for this happening was that the original wiring cable was too small to cope with large extended networks. The ethernet network's thick cable was replaced by a smaller thinner cable intended to reduce costs and make installation an easier process.
