I'm not a science student; have some basic knowledge of it. So, please explain in as much detail as possible. Thanks.

I have seen some old TV sets with a round knob to adjust volume. A guy told me that it's an analog volume control while the new TVs come with digital volume control where you adjust it by pressing a button. Is it true? What are the advantages of using digital over analog in this case? Isn't analog a good choice? Why? Because I suspect a digital control can only go from one fixed value to another fixed with no midway value. e.g. you can get from 2 to 3 to 4 but not from 2 to 2.5. But an analog gives a lot of flexibility between any two values. By the way, I don't know how these things work, just guessing.

Please guide me. Thank you for your time.
