Are medicare and medicaid the same?

I was not sure if medicare and medicaid were the same thing so i searched to this sight and found that they are not."You may think that Medicaid and Medicare are the same. Actually, they are two different programs. Medicaid is a state-run program that provides hospital and medical coverage for people with low income and little or no resources. Each state has its own rules about who is eligible and what is covered under Medicaid. Some people qualify for both Medicare and Medicaid. For more information about the Medicaid program, contact your local medical assistance agency, social services or welfare office."
