How to make a taxonomy vocabulary overview page with Drupal 7
If you refered that taxonomy term in a content type then a listing page is created by default.

For example if you created a taxonomy named Category  and terms inside it are


Knowledge
courage


If you created a content type and refered category taxonomy then listing page will be at category/knowledge , category/courage and so on

To display all the contents of the vocabulary then


  Create a view of type Node
  
  Add a display of type block or page according to your need
  
  Add your desired fields(CCK) along with a field Taxonomy: Term
  
  Add a filter Taxonomy: Vocabulary and select is one of operator and choose the
    particular vocabulary name.


This solution will include taxonomy terms associated with content node but filter according to the defined vocabulary in filter.
