Can someone explain "ground" to me?

Ok, I losely understand that with electronics the ground is connected to some wire that goes into the earth(?)

But how does a ground work in a portable since it has no connection to the earth? And could someone explain to me why electronics need a ground in simple terms?

I have an intrest in electrionics, and have done a little bit of soldering, but I don't completly understand the basics.

it's the negative. here's an example of how ground helps save space as opposed to separate -'s

in the top picture, "shared -" is ground. having ground instead of separate -'s not only saves space, but makes it a lot easier for engineirs to make PCBs and it works just as well

Try reading that. Basically, ground is a source of electrons (electricity). Without the electrons, nothing works.
