Great course. It is great for beginners and for people that may have forgotten a thing or two. The way it was taught makes it so much better than reading man pages or something else as dry and boring.
Apply yourself to these terms and concepts and you will gain knowledge that is presented in a very understandable way. Watch and rewatch the course videos and I promise it will all start making sense!

•This course had positives and negatives.
The positives are mainly the information covered which seems like a thorough syllabus of the subject of networking and overall i am satisfied with what I have learnt and grateful.
The main negative was how many of the lectures were structured and how the concepts were explained.
I understand my next point is based on personal learning preferences however I think the point is still valid.
My main gripe is how the lectures just tell us information and not really teach us the information. A good example of this was the ethernet frame lecture and subnetting lecture. The information was presented in a linear fashion, eg.
"An ethernet frame is (followed by definition), the structure of the frame is the header and payload, the header is x bits long, the next field is this, this field is used in the process named y, followed by a definition of process y"
Before I could gain an understand of the information, there would be new information explained in the video. By the time I am onto process Y (in my example)I have already forgotten about the payload and the previous information.
I think a more successful manner of presenting the information (now I am talking about many of the lectures in general) could of been by explaining the general structure of the frame and how it works then giving details about structure.
In practice I adapted by reading one line at a time, noting down and watching the video over, I found other videos on YouTube which were more successful in teaching me the subject in a more efficient manner, by first not describing the process in a technical manner, but more in a metaphorical manner so I understood the general concept. A good example of this could be how the TCP handshake was taught and how It could be improved.
Instead of just listing how the process works as in, first a syn packet is sent then a syn ack is sent back etc. You could, explain how TCP works in three steps by using no technical words,
First the computer asks the server can I connect to you?
The computer responds and a connection is made
Then data transfer happens.
Then the computer asks can i close the connection.
From this point, the technical details can the be explained on top of this understanding. Now I already know the purpose of the 3 way hand shake and 4 way hand shake, thus when the control flags are explained, it can be fitted upon the general guideline of how the tcp connections works.
Thanks for reading if you have.
