Schrodingers equation

What does it mean for the allowed energy states to be discrete (quantized) and have principle quantum numbers? We went over that in discussion but im a little confused.

I believe it just means that the energy states can not be decimal numbers, and can only be whole numbers like 1, 2, 3, etc. The electrons can not jump to the middle in between these energy levels, and if it is going to go up an energy level, it has to go up exactly that amount otherwise it doesn't work.
