But this was really good and really understandable. Great work mate. Thanks a lot for this!!

It receives ‘electrical’ signals from the wire, and transmits signals on to the wire.
Your WiFi NIC works the same way, receiving and transmitting ‘radio waves’ which are then interpreted as a series of 1’s and 0’s.”

What about Fiber Network Interface Card (NIC) do? Does it receive a light pulse signal and transmits as a series of 1’s and 0’s? Or is a Fiber Network Interface Card doesn’t exist?

I read it as a fiction book.
It is very easy. Very descriptive. Full of concept and beautifully design.
I love it very much.
Know i don’t have to remember anything because i understand it why.
Thank you.
God bless you.
