I watched this short video about the netstat command and found the topic very interesting. Where can I find more noob-friendly information about the theory of IP tables? Right now I’m interested to learn more within the context of Windows instead of Linux (so that I can follow along).

I’m very interested to learn how programs/services listen/operate in relation to firewalls and also antivirus software like malwarebytes and windows defender. (For example I thought that I had to specifically open a port in my router for a program to use, but when I use netstat I see that there are tons of programs/services running that are using all kinds of ports.)

The reason that I am asking here is because I would rather someone point me in the right direction than try to over-Google it and find too much irrelevant information. As a cytologist I could Google various cancer cells and be able to sort through everything that I see to prioritize relevant information, but that’s because I’m a professional in the field. I have no such experience with networking.
