What is Wordpress exactly?
It isn't a webhosting service.
Is it like a program built into Dreamhost?
Open Source Content Management System aka CMS... other CMS include say Drupal (Whitehouse.gov runs on this) or Joomla...
It basically is a framework to help you manage your content. Wordpress comes with it's own control panel. You can do basically EVERYTHING from there. Write posts, create users, add plugins, install themes etc... as well as manually edit the CSS file and such.
It also has a nifty auto update feature. So whenever a new version or a security update comes out you can just press one button, and boom update done!
Everyone from the RHCP to CNN use this shit. It's just an easy way to create a website. Wodpress.ORG is the official site for the software. Remember .ORG as .COM is a free to pay host deal that is a Wordpress.ORG offshoot.
WordPress names each of their releases after Jazz greats. They also do a video preview for each release.

WP can be manually installed and is it's own deal. It's so popular though that most hosts all have one click installs or use CPanel to help you install WP (or something similar) since it's so ubiquitous. So basically no technology is needed to install. CPanel or the like installs and hooks all of the shit like apache, mysql, and wordpress all together. Then you just go!
It's as easy as 1..2..3.. and so many people use it there are a gazillion websites you can use for examples, themes to pick from, plugins to add in, and tutorials for help!
PS: WordPress will blow your mind after you use it.
