301 is an HTTP status code that basically instructs search engines and browsers that a page has moved, permanently. If you've changed a file name, domain, folder path, whatever, a 301 redirect will update the search engines. This ensures your content remains indexed and available via search engines.

In addition, javascript, meta refresh tags, and some web-servers even support redirection management via conf files. If there's a particular redirect you'd like to know more about but can't seem to find any information, post a comment and I'll do my best to provide some guidance.
