In this course, we examine technologies for connecting all of the computers within a building. These technologies are called LANs.

Local Area Networks (LANs) are a way of implementing multidrop or multipoint data circuits within an office. LANs started to become popular in 1980, and have now become the standard method of implementing circuits to connect equipment.

One of the original requirements for a LAN was to connect computers in an office to a shared laser printer. This requirement has generalized to connectivity between devices and the sharing of resources, including hardware resources such as hard disks and surveillance cameras; information resources such as centralized databases; software resources such as network address configuration programs; communication resources such as WAN circuits and other resources.

Ethernet Switches, a.k.a. Layer 2 or LAN switches, creating broadcast domains with hardware; and VLANs, defining broadcast domains in software, are now the basis for the core of the telecom network: the backbone is now Optical Ethernet, no longer SONET and ATM.

The same Optical Ethernet technology is used for 10 Mb/s to 150 Mb/s fiber to the home or small office, and 40 Gigabit service to large office buildings.

Ethernet LANs are the standard method of implementing Layer 2 of the OSI Model, data links between two machines. This is the "Layer 2" story.

Taking this course, you'll gain a solid understanding of LANs:
• Ethernet and its bus topology
• Layer 2 technology
• CSMA-CD access control
• Broadcast domains
• MAC addresses
• MAC frames
• The IEEE 802 standards
• Evolution of Ethernet from 10BASE-T to Gig-E
• Hubs and switches
• LAN cables
• The TIA-568 cable categories
• What "bridging" means
• How a LAN switch works
• VLANs
and finishing with a preview of the next course: using routers to move frames between broadcast domains.

We'll cut through the jargon to demystify Ethernet, MAC addresses, LANs and VLANs, explaining the jargon and buzzwords, the underlying ideas, and how it all works together... in plain English.
