Data Base Doesn't connect

Hi! i downloaded sql developer yesterday. I have tried to run a data base conexion since yesterday. That is the error : Error de E/S: The Network Adapter could not establish the connection .Código de proveedor 17002

I was searching on google a lot, things about listener and tnsname, but when i downloaded the archive.zip i have no listener.ora or something like that, i was trying the command lsnrctl status, but doesnt exist on path because i have no listener, and i have no oracle folder too, just the unzip folder. I have to make a work for the university and i dont know how to do. Anybody has a solution?
Thanks

You need a database.

Of course you can create a database without virtualbox. If your machine meets the requirements for installing the oracle database software, then you can install directly on your machine. The cited article is discussing about how to get one up quickly, with the least chance of error. But really, the more important part of the cited article , and more directly related to your original question, is simply the fact that SQL Dev is just a database client. You still have to have a database to connect to, and creating that database is totally separate from and outside of SQL Dev.
