What really happens in the background that the users don’t see, that magically makes GMail send emails and Zoom make video conferencing possible?
In: Technology
So this analogy works best to explain email.
When you send an email, you are sending a letter via a series of computers to another one. So you write your letter, put it in an envelope, write the address on the envelope, put a stamp on it and put it the post box. That is you sending your letter. That’s what happens to an email up to it going to your outbox.
Once you’ve put the letter in the post box, the post courier comes and picks it up. They then take it back to the sorting office where the postcode dictates where the letter is going. It gets sorted in the sorting office with other letters going to the same area.
That is the process of email client sending your email to the other email client.
Finally another courier picks up the letter and takes it with them on their rounds. When the courier reaches the postcode on the letter, the letter is put through the recipients letterbox.
That is the process of the email arriving in the recipients inbox.

You can use the same analogy to explain zoom conferences and any other internet traffic.
With things like Zoom/Teams the process of sending a letter is repeated on a much quicker scale in order to send and receive audio and video from all participants.
