I just found this blog and wanted to share.

There are a lot of articles (41 pages) and they cover a lot of topics - for beginners and more advanced users. The ones I looked at are written in an understandable way and some of the ones I found interesting are listed below - they cover some of the more basic topics:
What is a tracking pixel?
What is my router’s IP address?
What is RFID blocking?
What is single sign-on (SSO)?
