I'm sure this is something so simple, but I've failed to find answer elsewhere, even doing several google searches "circle on circuit board", "diagram of circuit", etc...
What is the circle at the end of a wire\line on a circuit board? (the actual circuit board, not a diagram\drawing of one) What's it's function?
I could see where they might serve as connection points to some component, but I often see like at:

...in the upper left corner there is a short line with the circles at each end that don't seem to be leading to anything, what function might such an isolated wire serve?
Thanks in advance for any answers.
