Ethernet fundamentals

What you will learn:

You'll learn the history and evolution of Ethernet, understand the structure and facilities of Ethernet frames, explore the role and operation of switches, and discover how modern Ethernet networks are structured to provide resilience and performance. No prior networking knowledge is required.

 

By the end of this course you will be able to:

• describe the role of a local area network (LAN), giving typical applications.
• describe the role of the various bodies responsible for formulating Ethernet standards and the relationship between them.
• describe the role of the MAC protocol used by an Ethernet LAN.
• describe the role and operation of CSMA/CA and CSMA/CD in allowing devices to share the transmission medium of wireless and wired networks respectively.
• describe and compare the structure and facilities of the various types of Ethernet frame.
• describe the topology and features of Ethernet LANs from 100BASE-TX to 10GBASE-LR.
• describe and compare the operation, and facilities of Ethernet switches.
• explain the limitations of legacy equipment such as hubs.
• describe the role and operation of the "self-learning" facility of an Ethernet switch.
• describe the problems associated with network loops and describe methods of prevention.
• describe the benefits of a Virtual LAN and the significance of class of service indicators.
