Permalinks

According to WordPress.org’s codex permalinks are “the permanent URLs to your individual weblog posts”.  What makes Permalinks interesting is that you can create “pretty” permalinks (instead of having a series of numbers or symbols, the link is shorter and aesthetically pleasing).  To create pretty permalinks use mod _rewrite fuction (visit here for a more detailed explanation than I can possibly give).

Permalinks are essential because they provide a permanent way to access the material you are trying to link to.  If the links were not permanent then they would change over time and your content would be negatively affected.
