This question is asked multiple times every day on Answers. Dont' forget to use the Answers search box.
Your question is a little like "How do I do brain surgery?" or "How do I overhaul an engine?"
Until you learn the terminology, until you know the difference between a camshaft and a crankshaft, naming those items won't help you.
Your question is too general, and you haven't done your part yet. When you have a specific question about something you don't understand, we can help. But nobody can teach you how to invest in a paragraph or two. Trading is yet another world than investing, like comparing brain surgery to overhauling an engine. You have to learn to walk the Wall Street walk first.
Look at your local library for books on investing, you'll be surprised how many there are. Also there are ebooks online.
