The course begins by explaining the use of some of the devices found on Local Area Networks (LANs) such as switches, routers and hubs, and how each of these devices functions to allow for efficient communication on the LAN.

You will then learn about IP addresses and their functions and how they are broken down into Host ID and Network ID components. You will be introduced to network topologies such as Ring, Star, Bus and how they work. Next, you will learn about Ethernet; the most widely installed and the de facto standard LAN technology. You will learn about how different devices on an Ethernet network can communicate with each other using Frames.

The course then covers the seven layers of the OSI Model, the function and structure of each layer and how data is passed through the each of them to allow for communication. You will also be introduced to the TCP Model and you will learn about the differences and similarities between the OSI and TCP Model in terms of their structure.

This course is for any learners with an interest in computer networking. It will be of great interest to all learners who are considering doing professional computer networking exams or who are considering it as a career.
