The use of a bootloader allows us to avoid the use of external hardware programmers. (Burning the bootloader onto the chip, however, requires one of these external programmers.) Isn't the Arduino board itself the external hardware? So why would you need a bootloader then?

Bootloader? little confused here.

So what if I buy a seperate ATmega chip, I can't use it on Arduino then because I need to put a bootloader on it?
