Difference between Test Cases and Test Data

What is the basic difference between test cases and test data? Please explain this with an example.

A test case is a set of conditions or variables under which a tester will determine whether an application or software system is working correctly or not. Where test data is data which has been specifically identified for use in tests. For example, you want to develop a test-case for login functionality of Learning Management Systems. Set of conditions defined (Pre-condition, Step, Action, Expected Response, Pass/Fail, Comments, Post-conditions) is test case. When you give a user name and pasword in LMS to check login functionality then this user name and password is test data.
