16.2 Internet 101: Understanding How the Internet Works
The Internet is a network of networks. Internet service providers connect with one
another to share traffic, enabling any Internet-connected device to communicate with
any other.
Having multiple networks will reduce redundancy.
Many ISPs are big telecom companies like Verizon, Comcast, Rogers, Bell, AT&T
Uniform Resource Locator (URL)
URLs may list the application protocol, host name, domain name, path name, and file
name, in that order. Path and file names are case sensitive.
o Protocol: Enables communication by defining the format of data and rules for
exchange.
You don’t buy a domain name but can register it, paying for a renewable right to use
that domain name. Domains need to be registered within a generic top-level domain
such as “.com” or “.org” or within a two character country code top-level domain such
as “.uk,” “.ly,” or “.md.”
