What is difference between blog id and site id?

by

The going through the mu functions source I come across references to two different ids for sub-blogs – site id and blog ids. In what context is each used?

  • site_id = the ID of the parent site (the domain, eg. wordpress.com)
  • blog_id = the ID of the parent site’s blog(s) (usually sub-domains, eg mary.wordress.com)
