Docker Engine vs Docker Desktop 25.0.2

Hello, my question is whether or not I need to have Docker Engine running at the same time as Docker Desktop.

I installed Docker recently before seeing Mosh’s “Docker Tutorial for Beginners” video on YT. I noticed he stressed the fact you must have Docker Engine running.

I am running Version 25.0.2 , the latest version, it seems as if they’ve merged together but I am unsure.

Any info would be very much appreciated, thanks!

Originally Docker was made for Linux. It is called Docker Engine.
On Mac and PC there were adaptations such as Docker toolbox.
Currently we have Docker Desktop which is underneath a Linux virtual machine. That’s why Docker Engine must always be running.
So I don’t think they are merged.
