I'm reading about a book on general stuff about computers and I have a question about these somewhat seemingly complicated systems.
There are three types of internet access providers: ISP, Commercial Services, and Wireless ones
Next in the same chapter the book talks about the Internet Connections: POPOS, NAPs, Backbone, and Internet 2
The author relates these internet connections primarily to ISP, not the commercial services of which I think can also be related(or interconnected).
Can someone please solve this blurring connection in my mind?
Ex: Your journey onto the internet starts, in the caseof dial-up, with your client computer'smodem connecting via a local phone call to your internet service provider(ISP). <--Here can we not say ISP and commercial online services?
To avoid making its customers pay long-distance phone charges to connect, the ISP provides each customer with a point of present(POP)
