Permalinks are the permanent URLs to your individual pages and blog posts, as well as your category and tag archives. A permalink is the web address used to link to your content. The URL to each post should be permanent and never change — hence the name permalink.
The Settings Permalinks Screen allows you to choose your default permalink structure. You can choose from common settings or create custom URL structures.
You must click the Save Changes button at the bottom of the screen for new settings to take effect.
By default, WordPress uses web URLs which have day and name in them; however, WordPress offers you the ability to create a custom URL structure for your permalinks and archives. This can improve the aesthetics, usability, and forward-compatibility of your links.
For a more in-depth description of the way this structure is specified, see the Using Permalinks article. For an introduction to Permalinks, read the Pretty Permalinks section of Introduction to Blogging.

Optional
You may enter custom bases for your category and tag URLs here. For example, using /topics/ as your category base would make your category links like http://example.org/topics/unca.... If you leave these blank the defaults will be used. Again, see the Permalink Structure Tags.
