Vlog about basics in IT industry technologies and how they work

I recently met a sales person who wants to get a general understanding of IT industry so he can talk about basic things like: mobile apps, backend, API, how they communicate, what’s cloud, different technologies, things to be aware of etc.

Also, my wife got into UI/UX now and really needs to understand things she doesn’t know they exist or how these work. What does search work? Can it take longer to return a search result? What’s a server, backend, API and why a server can go down?

These are only 2 examples but there are hundreds of thousands of entrepreneurs, sales people, investors etc who need to get a good understanding of how things work in our virtual tech based society. It’s so important that all of these must be taught in school.
