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.

Taking antibiotics all at once could have serious implications for your liver. In fact even use of them in the way they are prescribed is a common factor in liver injury. Please don’t take antibiotics all at once ever.
