The Doctor of Science degree (DSc or ScD) is recognized by the U.S. Dept. of Education as a research doctorate equivalent to the Ph.D. Sometimes, in the U.S., the Doctor of Science is awarded as an honorary degree. Outside the U.S. it is an earned doctorate (as me again states above).
A Ph.D. degree is a Doctor of Philosophy, or philosophiae doctor in the original Latin. Philosophy means love of knowledge, and a Ph.D. is the highest graduate degree in the U.S. It's available in many fields, including the humanities, social sciences, natural sciences, business and engineering.
