ELI5: what is the difference between stereo sound, Dolby sound, and all the other types of sound?

What’s the difference now? Come on fellas help me out.
gpt
Mono (1) - the sound comes from all the speakers and sound the same.

Stereo (2) - Two different sounds played on two (or more) speakers.

Stereo w/ bass (2.1) - Same as stereo, but there's a rumbly box making shaky noises.

Dolby Surround Sound - Dolby's version of many sounds coming from many directions. (5.1 - 5 speakers and a rumbly box, 7.1 - 7 speakers and rumbly box.
