WordPress blog script is the actual blogging engine. You need this to publish your posts/pages. WordPress theme is a way for you to change the look of your blog. WordPress plugins are ways to add functionality to your blog.

Wordpress.com is a free blog hosting source if you don't own a website. Wordpress.org is the homepage for the CMS that you can install on your own website.
