Oracle Database Discussions

I have a query as to how to connect to an Oracle server running on Linux from a Windows machine, I am listing the requirements point-wise:

1) Oracle client would be required on the Windows machine.
2) Also a local tnsnames.ora entry would need to be put on the Windows machine with an entry pointing to the Oracle installation on the Linux server.
3) Then from Windows client, SQL connection can be opened and values of username & password of Oracle server schema along with tnsnames.ora entry can be put. The result should be an SQL prompt.

I hope my question is clear of the steps for connecting Oracle server running on Linux from a Windows machine.

Please revert with the reply to my query.
