In the mid-nineties, an anecdote made fun of one of the Spice Girls, I forget which. She saw a computer with a web browser on it, and she said: "Can I have that? Can I have an Internet?"
This video shows that a minority of people using the Internet knows what a "browser" is. They often confuse it with a search engine. TidBITS has an article commenting.
Years ago I was in a writers' group, and I made a satirical poem about technology. Despite the fact that at that point I was a newbie myself, and despite that I deleted words which I thought the broader audience might not know, the poem caused massive confusion in the group, they hardly knew any of the terms I'd used.
I also notice how many people even today confuse the terms "web site", "blog", "email list", "newsletter", etc.
I really hope I'll never need to take a job as tech supporter.
About two years ago some so-called "child reporters" asked our top politicians about "internet" (see youtube, of course in German).
One of the questions they asked our minister of justice (Brigitte Zypries) was:
"Which browser do you use?"
Her answer was, after some hesitating:
"Browser? What is a browser?"
Since then, the question "What is a browser?" is a running gag all over the internet communities in Germany.
One suggestion is, that she has thought about a shower head, because in German it's also called "Brause".
She may also have thought about sherbet, because that is also called "Brause" in German.
(Together with the other answers it shows that our politicians have no understanding at all about internet, but sadly they decide about it's future, mostly by trying to keep it under control, which leads unavoidably to censorship ...)
