I want to start doing my own investing. Where do I start to do research to learn everything I need?

I want to be able to set up a brokerage account and learn what things like GDP mean, be able to read and understand what Penny stocks, Bonds, buying silver bonds vs. buying silver and everything I haven't mentioned because I don't know enough to ask? I have to be able to learn from home or online. Can anyone head me in the right direction to learn what I need?
