CSMA CD Technology
CSMA/CD Collision Detection and Avoidance In recent years, Ethernet networks have popped up in homes, business, and all over the world due to the simplicity of Ethernet standards, low cost of equipment, and ease of cabling. ... Within this document, the author will examine one such technology that ensures Ethernet data is transmitted and received properly without hogging network bandwidth with unnecessary data collisions. This document will explain the technology used by Ethernet standards to avoid collisions, ensure accurate data transport, and minimize the chance of more than one systems transmitting data on the same line at any given time. Several drawbacks and benefits of this technology will be discussed, and a brief conclusion will summarize the topics and ideas presented within this paper. CSMA/CD Technology Carrier Sense Multiple Access/Collision Detection, more commonly referred to as CSMA/CD, is the standard by which Ethernet networks ensure that only one system or device transmits data across the network bus at any given time. ... CSMA/CD, as its name implies, uses proactive sensing of traffic on the Ethernet bus medium. Before a system or device attached to the network attempts to send data, CSMA/CD ÒlooksÓ into the network to see if any other device is currently transmitting or receiving data.
