SQL+ login

I just installed Oracle9.2 Windows NT on my system ( Windows XP professional). When I tried to open up SQL plus it asks for a username, password and Host string. I want to know where I can find the username and password for SQL. It would be gr8 if any one can help me. I'm just starting off with SQL. Any kind of help would be appreciated.
Thank you all in advance
