Eli5 – why do you take antibiotics as a course and not all at once?

Question

I’ve just started an antibiotics course which is 4 times a day for 10 days and that got me wondering if they would be just as effective if I took them all and why not.

You could stab a person one time, and they might be ok. But it’s you stab them 40 times over 10 days, they are going to be a lot worse off.
