DO YOUR OWN BASIC RESEARCH.
I hope the sparkles got your attention.
This community is not here to save you from the tedium of looking up information; it's here to help you when you can't find the information that you need on your own.
Use Google. Use Wikipedia. If your first search doesn't work, try other terms, and keep trying for more than two minutes. Don't make me - or other annoyed members - smack you for being lazy.
