New to jQuery

New to jQuery

Good Day All,
 
Couple of things.
 
1.  Is this the correct way to embed jquery on a webpage?
 
<!DOCTYPE html>
<html>
<head>
  <title>Getting Started with jQuery</title>
<script type="text/javascript" src=" http://ajax.aspnetcdn.com/ajax/jquery.ui/1.11.2/jquery-
ui.min.js"></script>
<script type="text/javascript" src="script14.js"></script>
</head>
<body>
  <h1>Getting Started with jQuery</h1>
</body>
</html>
 
2.  I also created a script.js file is this also correct?
 
jquery(document).ready(function() {
   alert("jquery is working!");
});
 
3.  If both of these are corect why does it not show the alert message when I load the web page?
 
Thanks in advance.
