Course description

In this course we'll discuss the implementations of two major kinds of networks. The first is the implementation of Ethernet networks. Ethernet is the most common standard in use today for Local Area Networks and thus something you will deal with on a daily basis. We will then jump into another type of implementation, the wireless networks. Next we'll look at the ISO standard OSI / RM. This reference model, as you will see, provides a standard framework for network technicians, design engineers, and developers to utilize. In some ways it helps to identify the capabilities of a protocol or network device and as such can be useful when diagnosing problems or choosing a device to implement on the network. In other ways it helps us as humans understand all that is involved in data transfer on the network. We will also look at the most popular protocol model known as TCP/IP and discuss its function and relation to the OSI Model.


This course assumes the user has some experience with computer hardware, software, and understands the concept of a computer network. The user should have viewed CompTIA NET+ Cert: Media and Hardware before taking this course.
