its because other library also use $ so there will be conflict use jQuery.noConflict()

jQuery.noConflict();
(function($) { 
  $(function() {
    // more code using $ as alias to jQuery
  });
})(jQuery);

or like 

<script type="text/javascript" src="other_lib.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
  $.noConflict();
  jQuery(document).ready(function($) {
    // Code that uses jQuery's $ can follow here.
  });
  // Code that uses other library's $ can follow here.
</script>

You might have another library which also makes use of $.

In which case you can make use of jQuery.noConflict.()

var j = jQuery.noConflict();
j(function () {
   j("#tabs").tabs();
});

The reason might be conflict with other plugins like prototype for example that also uses the $ sign

The basic reason is that the $ variable is also used by others javascript framework like Prototypejs and Mootools.

So if you want to use both jQuery and Mootools for instance, you should avoid the use of $.
