Diploma mills are schools that are more interested in taking your money than providing you with a quality education. You need to know how to protect yourself as a consumer.
The Higher Education Opportunity Act defines a diploma mill as follows:
DIPLOMA MILL- The term `diploma mill’ means an entity that–
(A)(i) offers, for a fee, degrees, diplomas, or certificates, that may be used to represent to the general public that the individual possessing such a degree, diploma, or certificate has completed a program of postsecondary education or training; and (ii) requires such individual to complete little or no education or coursework to obtain such degree, diploma, or certificate; and
(B) lacks accreditation by an accrediting agency or association that is recognized as an accrediting agency or association of institutions of higher education (as such term is defined in section 102) by–
(i) the Secretary pursuant to subpart 2 of part H of title IV; or (ii) a Federal agency, State government, or other organization or association that recognizes accrediting agencies or associations.

The dictionary defines a diploma mill as:
An institution of higher education operating without supervision of a state or professional agency and granting diplomas which are either fraudulent or because of the lack of proper standards worthless. – Webster’s Third New International Dictionary
