Description
Computer Networks Fundamentals is a course that will help you get off the ground with your Computer Networks knowledge, with easy-to-understand theoretical lessons and some practical examples. In this course, the OSI (Open Systems Interconnection) model is used, following its 7 layers:
1. Physical Layer (L1)
2. Data Link Layer (L2)
3. Network Layer (L3)
4. Transport Layer (L4)
5. Session Layer (L5)
6. Presentation Layer (L6)
7. Application Layer (L7)
We will use that same order, and as a bonus, after we've thoroughly covered all 7 OSI layers, we'll also cover the topics of Computer Network Security, Mobile, and Wireless Networks too.
Computer networking knowledge is likely to improve your career prospects. Network professionals may work as network engineers or network architects, computer security specialists, or network and computer systems. Either way, opportunities in this field are plentiful.
You may also use this material as an introduction to Computer Network Security, which has been in focus lately. For the jobs offered in that area, knowing Computer Networks fundamentals is a mandatory pre-requisite, and will greatly improve your chances of getting a role in cybersecurity some day.
As in every Cyber Quince course, you're welcome to ask questions both in the Q&A section, and via direct messages. Any suggestions and requests for additional topics to be covered will also be appreciated!

As a computer science teacher, I created several e-learning courses and my students loved it. I quickly realized that even the best students used these materials, as they preffered knowing that they'll be able to review any lesson at any time (especially before exams ;)). This inspired me to create simple, straight to-the-point courses even for advanced subjects.
I left my academic career for a job in Cyber Security, in a multi-national Telecom. Now I'd like to share my knowledge, so if there's any security/network topic you need help with, let me know and I might be able to create a course!
