  Ethernet
The original Ethernet was developed as an experimental coaxial cable network in the 1970s by Xerox Corporation to operate with a data rate of 3 Mbps using a carrier sense multiple access collision detect (CSMA/CD) protocol for LANs with sporadic but occasionally heavy traffic requirements.
Increasing the Ethernet transmission rate by a factor of ten over 10Base-T was not a simple task, and the effort resulted in the development of three separate physical layer standards for 100 Mbps over UTP cable: 100Base-TX and 100Base-T4 in 1995, and 100Base-T2 in 1997.
Because each port provides access to a high-speed network bridge (the switch), the collision domain in the network is reduced to a series of small domains in which the number of participants is reduced to two—the switch port and the connected NIC (see Figure 7-28).

 Diagram An Ethernet Network - Perfect network design software with free ethernet network diagram examples and templates
Whether you're designing a simple Ethernet network or documenting a large and complex one, you can use the improved Ethernet shape in EDraw Network Diagrammer to get the job done quickly.
The connectors on the Ethernet shape attach easily to the updated device shapes in EDraw, and they remain attached, even when you move them.
When the device shape is correctly connected to the Ethernet shape, the connection point turns red, indicating that it is glued.

  Network Instruments | Ethernet Analysis Technologies
And since the entire Observer family is based on the Network Instruments Distributed Network Analysis (NI-DNA™) architecture—it is simple to monitor all segments of the network simultaneously, from any location, through a single user interface.
To capture network data, direct a switch’s SPAN session to a Network Instruments Ethernet probe.
Ethernet probes report that data to Observer® consoles located anywhere on the network for comprehensive, real-time analysis.

  Creating a small Ethernet network
Ethernet is a common solution for connecting computers to the Internet and for sharing data between computers.
Ethernet cable - Each device you want to connect to your Ethernet network requires a standard RJ-45 twisted pair cable, sometimes called a patch cable.
This type of network may be used for sharing files, playing network video games, or printing to a printer that has Ethernet, for example.

  RPR Soups Up Sonet and Ethernet - Network Infrastructure - Network Computing
Ethernet is king of corporate networking and Sonet reigns in the carrier space, but both are less than perfect.
Including RPR on an Ethernet network is slightly different and may require a new network on top of the existing Ethernet.
RPR supports network device and node autodiscovery; new network nodes announce themselves to their direct neighbors with control messages and distribute changes in their settings or topologies.

  Ethernet - Wikipedia, the free encyclopedia
Ethernet is a large and diverse family of frame-based computer networking technologies for local area networks (LANs).
Ethernet was originally based on the idea of computers communicating over a shared coaxial cable acting as a broadcast transmission medium.
Networking standards that are not part of the IEEE 802.3 Ethernet standard, but support the Ethernet frame format, and are capable of interoperating with it.

 Ethernet hub - Wikipedia, the free encyclopedia
An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fibre optic Ethernet devices together, making them act as a single segment.
Ethernet hubs are also responsible for forwarding a jam signal to all ports if it detects a collision.
A hubbed Ethernet network behaves like a shared-medium, that is only one device can successfully transmit at a time and each host remains responsible for collision detection and retransmission.

 What is Ethernet? - a definition from Whatis.com - see also: Alohanet
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 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.
Ethernet was so- named to describe the way that cabling, also a passive medium, could similarly carry data everywhere throughout the network.

 Halfbakery: Multiple tokens on an ethernet network
What a token network does is send a little token around and when a computer receives the token it is able to send or receive information across the network.
One big problem with a token-ring network is that either the computers have to be physically wired in a "ring" configuration, or the computers have to collectively know the identity of everybody on the network.
Ethernet imposes no such restrictions: computers may be added to the network without any other computer needing to have any knowledge about them.

Ethernet is the IEEE 802.3 series standard, based on the CSMA/CD access method that provides two or more stations to share a common cabling system.
There are a number of physical networking components specified in the IEEE 802.3 specification, but many of those early physical networking components are not used in most modern Ethernet networks.
In Ethernet networks, any frame shorter than the minimum 64 bytes but with a valid CRC is considered a runt.

A computer network is a group of computers and other associated devices, such as printers, fax machines, and modems, that are connected to one another so they can share resources and information.
Ethernet and Fast Ethernet are local area network (LAN) protocols, or specifications, that define the signaling of the network and specify how data is placed on and retrieved from the network.
The maximum Ethernet cable length allowed between the  NIC and the network device to which it is connected is 328 feet (100 meters).

 Ethernet
Ethernet was developed by the Xerox Corporation's Palo Alto Research Centre (known colloquially as Xerox PARC) in 1972 and was probably the first true LAN to be introduced.
Ethernet uses a simple Carrier-Sense Multiple Access protocol with Collision Detection (CSMA/CD) to prevent two computers trying to transmit at the same time (or more correctly to ensure both computers retransmit any frames which are corrupted by simultaneous transmission).
Ethernet LANs may be implemented using a variety of media (not just the coaxial cable described above).

A direct serial AppleTalk network uses an Apple printer cable to connect either the printer or modem port of one Macintosh to the printer or serial port of another Macintosh.
Then phone cable is used to connect the first converter box to the second, connect the second converter box to the third, etc. At the end of the chain, use a resistor, which is provided with the phone net converter boxes, to "terminate" the open RJ-11 connector.
The main considerations you should take into account when purchasing an Ethernet hub, are that the hub has enough ports to connect all your computers into it, and that the hub is rated at the same speed as the NICs in your computers (10BaseT, or 10/100 BaseT).
