It is so popular that if you buy a network card to install on your machine, you will get an Ethernet card, unless you ask for something different, if of course that different protocol is available.Įthernet has evolved over the years.

If you want to see what a coaxial cable is like, look at the thick cable that links your TV antenna to your TV set.Įthernet is by far the most popular LAN protocol used today. Some Ethernet networks use coaxial cables, but that’s rarer, and present in rather large LANs, which span over areas between buildings. The wires used for a LAN are mostly those headed by an RJ-45 jack, which is similar to the jack plugged into your telephone set, but twice as big. It uses wires (meaning it is not a wireless technology).
Ethernet was so- named to describe the way that cabling, also a passive medium, could similarly carry data everywhere throughout the network.Įthernet is a protocol that controls the way data is transmitted over a local area network (LAN). 10-Gigabit Ethernet provides up to 10 billion bits per second.Įthernet was named by Robert Metcalfe, one of its developers, for the passive substance called “luminiferous (light-transmitting) ether” that was once thought to pervade the universe, carrying light throughout. Gigabit Ethernet provides an even higher level of backbone support at 1000 megabits per second (1 gigabit or 1 billion bits per second). Devices are connected to the cable and compvce for access using a Carrier Sense Multiple Access with Collision Dvcection (CSMA/CD ) protocol.įast Ethernet or 100BASE-T provides transmission speeds up to 100 megabits per second and is typically used for LAN backbone systems, supporting workstations with 10BASE-T cards. The most commonly installed Ethernet systems are called 10BASE-T and provide transmission speeds up to 10 Mbps. An Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires. Specified in a standard, IEEE 802.3, Ethernet was originally developed by Xerox from an earlier specification called Alohanet(for the Palo Alto Research Center Aloha network) and then developed further by Xerox, DEC, and Intel.
Ethernet is the most widely-installed local area network ( LAN) technology.
