We are referring to url aliases. A url alias is a replacement url for another url. Usually this is done to make things easier and make more sense for you and the people browsing your site, not to mention the search engines. The default urls usually have wierd stuff like "?q=node" but drupal is very nice to convert this sort of thing into something that makes sense.

Below are useful built-in aliases, ready to take you to important pages. Just type the alias into your browser's address bar, after <your site domain>.

 Drupal aliases

The following aliases come courtesy of Drupal:

The user login page. The first page you need as an administrator!

/user

List of registered users, with links to each individual user page.

/profile

Another way to get to individual user pages, by user number. The chief "ID 1" administrator's page is at /user/1; later users have later numbers.

/user/1, /user/2, /user/3, etc.

The main Administer page, containing links to all the forms you need to manage your site.

/admin

Your site's Contact form, if the site is set up to use one.

/contact

Your site's main Forums page, if the site is set up for forums.

/forum

Your site's main Polls page, if the site is set up to use polls.

/poll

All blogs on the site.

/blog

The site's default front page, if another specific front page has not been set. (It's "/node" because the front page, by default, is a list of all front-page-promoted nodes.)

/node

Individual nodes, using the numbers automatically given them upon creation.

/node/1, /node/2, /node/3, etc.

Page listing all nodes tagged with the Term bearing the number. See Terms, Vocabularies, and Categories: "Tagging" Your Content.

/taxonomy/term/1, /taxonomy/term/2, etc.

List of posts, in order of posting.

/tracker
