Hello everyone!

I would like to get suggestions on the particular courses to take on the above subject. I am currently a data protection analyst and understanding systems network is important.

I want to understand networks within an organization and how information flows. For information security and cyber security, I know the courses to take on udemy. But first, I want to understand networks.

Cheers

If you mean that you want to understand how networks work (4 layers of the internet, IP addressing, Transfer protocols e.t.c) then there's a Stanford course online which you can take. https://lagunita.stanford.edu/courses/Engineering/Networking-SP/SelfPaced/courseware

The Stanford course is free.
