Computer Networking - Local Area Networks and the OSI Model
The 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.
The course begins by introducing 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 then learn about the functions of IP addresses and how they are broken down into Network ID and Host ID components. You will be introduced to the different network topologies such as Star, Bus, Ring and how they function. Next you will learn about Ethernet which is the de facto standard and most widely installed LAN technology. You will learn how devices on an Ethernet network communicate with each other using Frames.
The course then moves on to explain the seven layers of the OSI Model. You will learn about the structure and function of each layer and how data is passed through the seven layers to allow two devices communicate with each other. You will also be introduced to the TCP Model and you will learn about the similarities and differences between the OSI Model and the TCP Model in terms of their structure and functions.
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.
Having completed this course you will be able to:
- Define what Local Area Network (LAN) means.
- Describe the key devices found on a LAN.
- Explain how Hubs, Switches and Routers function.
- Describe how Ethernet functions.
- Describe the structure and function of IP Addresses.
- List the seven layers of the OSI Model.
- Describe the functions of each layer of the OSI Model.
- List the four layers of the TCP Model.
- Describe the functions of each layer of the TCP Model.
- Explain the similarities and differences between the OSI Model and the TCP Model.
