Answer 1

you can think of
“normal internet” or “interconnected computer networks” as a mesh of roads/highways
“private networks” would then be roads in a gated community, to access those you get controlled.
“intranet” refers to the service provided in that gated community
“extranet” to services provided by that gated community to outsiders
