Newbie needs help with USB Loader GX

[A Random Moment]

Hello I'm new here. Actually, I'm new to the whole Wii Hacking thing in general.

I just wanted to know why are there different IOS versions of USB Loader GX? What exactly is an "IOS"? And which version of USB Loader GX should I download?

Try not to use any complicated jargon, but just keep things simple. For the most part I'm a quick learner, and I'm just need someone to show me the ropes.
Thanks
