Permalinks

Permalinks are the permanent URLs to your individual weblog posts, as well as categories and other lists of weblog postings. A permalink is what another weblogger will use to link to your article (or section), or how you might send a link to your story in an e-mail message. The URL to each post should be permanent and never change — hence permalink. Sometimes you can hear the word flush the permalinks, that's nothing it only needs to press save changes at Settings > Permalinks to refresh or flush the permalinks of your domain.
