The ALISON free online course “Computer Networking – Local Area Networks and the OSI Model” introduces the key devices found on local area networks (LANs) and the structure of different types of LANs. It also explains the seven layers of the OSI model that allow devices on networks communicate with each other.
This course will be of interest to all learners who would like to learn more about computer networking, in particular, the structure and function of LANs, and how the OSI Module allows devices on a LAN communicate with each other. It will be of great interest to all learners who are considering computer networking as a career or who are considering doing professional computer networking exams.
Computer Networking – Local Area Networks and the OSI Model – Course Content
The introduces you to the key devices found on LANs such as hubs, switches and routers, and how each of these devices functions to allow for effective and efficient communication on the LAN. You will learn about the functions of IP addresses, the different network topologies such as Star, Bus, Ring and how they function, and how devices on an Ethernet network communicate with each other using Frames. The course also explains the seven layers of the OSI Model.
The course includes the following topics:
- What a Local Area Network (LAN) is;
- The key devices found on a LAN;
- How Hubs, Switches, and Routers function;
- How Ethernet functions;
- The structure and function of IP Addresses;
- The seven layers of the OSI Model and their functions;
- The four layers of the TCP Model and their functions;
- The similarities and differences between the OSI Model and the TCP Model.
