Totally depends what you want to do really.
If you want to build your website without anything like dynamic stuff & database driven, forums etc... you can normally just stick with the webspace you got from your ISP combined with for example: a free .tk domain.
If you want php capability you might want to have a look here: Free PHP & MySQL hosting. Of course you could also combine these with a free .tk domain.
If asp is your flavour there are also free solutions for that online.
But maybe you can tell us what you are exactly planning to do so we can give you some more "directed" advice
