Overview:

As a network technician, you will frequently be involved with installing, configuring, and troubleshooting Ethernet network interfaces and transceivers. A network interface is the means by which a node is connected to the media and exchanges data with other network hosts. This involves both a physical connection to the network media and the use of a data link protocol such as Ethernet to perform addressing and framing. Understanding the properties of these components is essential for selecting appropriate products and configuring them correctly.
