Understanding how 10/100Base-T Ethernet operates

“Since the late 1990s, 10/100Base-T Ethernet (also known as IEEE 802.3 and CSMA/CD) has become the de facto standard for local area networks. We’re going to look at the elements involved in using Ethernet in a 10/100Base-T network, including the components of a frame, how Ethernet technology functions, and where this suite of technologies fits into the OSI reference model.”
