What's the difference between a Single root and a Chained root SSL cert?

Some Certification Authorities, like Comodo, do not have a Trusted Root CA certificate present in browsers, therefore they need a "chained root" in order for their certificates to be trusted - essentially a CA with a Trusted Root CA certificate issues a "chained" certificate which "inherits" the browser recognition of the Trusted Root CA. These SSL certificates are known as "chained root" SSL certificates.

Installation of chained root certificates are more complex and some web servers are not compatible with chained root certificates.
