ELI5: Why is computer keyboard "qwerty" and not "abcdef"?

Or qwertz (e.g. Europe).

I hope you know what I mean. Why they put the letters in this order?

In the days of typewriters, the keys were alphabetically ordered.  However this caused some keys to get jammed up, or more frequent typos (remember,  typewriter, you cant just hit backspace), due to frequently used letters being too close together. 

So they rearranged the letters into the qwerty board to space the well used letters apart more.  This cut back on jams and typos and was carried over to computer keyboards.
