Unlike wi-fi (wireless fidelity), an Ethernet needs a cable to transmit chunks of data called "frames." This cable is usually called a category five (Cat5) or category six (Cat6) cable. They are eight to 16 coaxial copper or fiber optic wires that are paired up and twisted together. All of the computers in an Ethernet need to be... more »
When the Ethernet was officially recognized as a network standard by the Institute of Electrical and Electronics Engineers (IEEE) in 1985, the Ethernet Card quickly followed as the widely accepted means for taking advantage of such technology. more »
Ethernet cards are a necessary part of home networking and are required for broadband Internet. Networked computers can share resources, including files and attached devices like printers and external hard drives. With the rise of high-speed Internet, almost all computers include a built-in Ethernet interface. However, Ethernet cards... more »
Ethernet technology is based on the idea of computers communicating with one another over a shared network. For the layered communication in computer network protocol, ethernet is the backbone. An ethernet network works by broadcasting signals in the form of action and protocol information by using a common signal address. Several... more »
Surfing the web is one of the most popular things to do on a computer. If your computer doesn't have a built in capability for a high speed Internet connection, then consider getting an Ethernet card. It will quickly add this feature to your computer and allow you to browse the web for fun, business, or research. more »

Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether. It defines a number of wiring and signaling standards for the Physical Layer of the OSI networking model, through means of network access at the Media Access Control (MAC) /Data Link Layer, and a common addressing format.
Ethernet is standardized as IEEE 802.3. The combination of the twisted pair versions of Ethernet for connecting end systems to the network, along with the fiber optic versions for site backbones, is the most widespread wired LAN technology. It has been in use from around 1980 to the present, largely replacing competing LAN standards such as token ring, FDDI, and ARCNET.
History
Ethernet was originally developed at Xerox PARC in 1973–1975. In 1975, Xerox filed a patent application listing Robert Metcalfe, David Boggs, Chuck Thacker and Butler Lampson as inventors, "Multipoint data communication system (with collision detection)". In 1976, after the system was deployed at PARC, Metcalfe and Boggs published a seminal paper.
The experimental Ethernet described in the 1976 paper ran at 3,000,000 bits per second (3 Mbit/s) and had eight-bit destination and source address fields, so the original Ethernet addresses were not the MAC addresses they are today. By software convention, the 16 bits after the destination and source address fields specified a "packet type", but, as the paper says, "different protocols use disjoint sets of packet types". Thus the original packet types could vary within each different protocol, rather than the packet type in the current Ethernet standard which specifies the protocol being used.
Metcalfe left Xerox in 1979 to promote the use of personal computers and local area networks (LANs), forming 3Com. He convinced DEC, Intel, and Xerox to work together to promote Ethernet as a standard, the so-called "DIX" standard, for "Digital/ read more at » http://en.wikipedia.org/wiki/Ethernet
