If you want to work with your Drupal site on local computer good decision is WAMP5 Server that installs automatically Apache 1.3.31 ,PHP5, MySQL database ,PHPmyadmin and SQLitemanager on your computer. After installation check if it works properly on http://localhost and add to host file (C:WINDOWSsystem32driversetchosts) address of your site, for example loc.n1.development.yourdomian.com
