Should we take the Jason Seifer's course?
Is it recommended or obligatory to take the Jason Seifer's course, which is mentioned amng the "Teacher's notes"? If yes, immediately after the "How Web works" course? Or we can do it anytime?

You've already had the introduction to DNS. Depending on how you use your computer, that might get you by for now.
The Technology Foundations course will go into more detail about it (and about digital graphics). You can take it anytime you want a more thorough understanding of either or both of those concepts.
