Understanding Ethernet Networking

Ethernet refers to the family of Local Area Network implementation that was jointly developed by Digital Equipment Corporation, Intel Corporation and Xerox Corporation. It consists of certain specifications and standards as well as hardware devices and components.

Ethernet Connection

The Ethernet protocol provides for a verity of cabling options, one of which is a specification referred to as 10Base5. Connecting cable is known as AUI (Attachment Unit Interface) and network attachment device is known as Media Attachment Unit (MAU) rather than transceiver.
CSMA/CD

Ethernet is a baseband LAN specification invented by Xerox corporation operates at 10 Mbps using CSMA/CD (Carrier Sense Multiple Access Collision Detection).

As a contention-based environment Ethernet allows any station on the network to transmit when ever the Ethernet network is quite. Collisions could be found whenever stations listen for traffic and hear nothing and transmit regularly. In this situation both types of transmissions are damaged and device should transmit later. Back-off algorithm is used whenever colliding stations should retransmit data.

Ethernet Network Design

Ethernet was designed to serve in network with sporadic, occasionally heavy traffic requirements. A network using Ethernet is usually considered as a low cost LAN.

Layer 1 and Layer 2 of OSI model related services are provided by Ethernet.

For creating an Ethernet network, you have usually implemented a network interface card on a primary circuit board. Cabling conventions of Ethernet describe use of transceiver for attaching cable to physical medium. Transceiver may perform some physical layer functions such as collision and detection. The transceiver cable connects end stations to a transceiver.
