Learn about the inner workings of Ethernet in this informative 27-minute video presentation. Explore the OSI model, major concerns of Ethernet, and various cable types including twisted pair. Discover the principles of differential signaling, common-mode rejection, and pulse-amplitude modulation. Understand collision sensing, full-duplex communication, and network topology. Dive into the structure of Layer 1 packets and Layer 2 frames, including MAC addresses and the Address Resolution Protocol. Gain insights into how gigabits of data are reliably transmitted through unshielded cables, enabling everyday activities like watching online videos.
