Computers communicate with each other over a network by using a pre-established set of communications protocols such as TCP/IP. It’s important to understand those protocols, and how IP addresses are assigned within a network. Most networks require cabling, and it’s important to understand what cabling options are available, and when to use each type. This course covers network protocols, and goes into detail on setting up an IP addressing scheme using either IPv4 or IPv6. It also describes all of the different network cabling options, along with the cable connectors that interface with them.

Target Audience
This path is intended for anyone who wishes to enter the IT professional field, and requires entry-level training to get them started with a career in technical support.
