ETFs are just investment funds you can buy and sell in the stock market, with their own symbol and everything just like any other stocks.
Index (passive) funds track an index, instead of trying to outperform the market.
You can have passive funds that are not ETFs (do not appear as a symbol in the stock market, have to go through a bank or whatever to buy shares), and active funds that are ETFs (actively managed).
