Once ive uploaded all my images and html...need help

Hello, very new to this setting up a website business and am really teaching myself, so can anyone help...
I have uploaded all the html files and images etc through the SmartFTP, loged in, password done and address too. Is this all i need to do? how long until i can see my website up and running?

Any help would be really appreciated (in english rather than computer jargon if you can!)

Thanks,
