S&P/DOW vs other index funds

I've been digging deep in investment security education, and I'm stuck on indexes. Specifically, the difference between major index funds like S&P/DOW versus mutual funds. I've been trying to figure out the role each plays to better understand how to think about them.

I'm very much a noob, so take it easy on me if I'm way off on my question.

Thanks
