selenium firefox, chrome, IE driver requirements in python [duplicate]

This question already has an answer here:

• Python : no module named selenium 1 answer

If I would like to use one of those drivers, what should I do before using it? I mean what should I install on a fresh installed Windows. On the pc is only python installed and selenium with "pip install -U selenium". Do I need install Chrome web browser to using chrome driver? Do I need download firefox driver for using it or it comes with "pip install -U selenium" command and built in? And the same question for firefox-> do I need download Firefox web browser to use Firefox driver? And finally the same questions for IE, except the download IE question, because IE comes with Windows os. Thank you.
