What exactly is socialized health insurance?

I have heard much, but I still am not fond of what it generally is. Please explain. Thank you!

Alice, a socialized health care system in America would be most beneficial to the millions who cannot get any medical coverage. Medical and pharmaceutical costs would be reduced to an affordable level. An American socialized health insurance plan run via the US Government would provide free health care to Americans that would be revenued through higher taxes and not cover elective treatments. This would ensure that all Americans received the healthcare treatment they needed to stay healthy. Right now the average American has to do without health insurance in many cases. When there has to be a choice between feeding your family and having medical coverage most choose to eat. The American that falls through the income crack has fewer options than any other group of American. Hopefully someday all Americans will be able to get their medical needs met no matter what income bracket they come from. Hope I answered your question.
