After consulting the web link above or a book at the library or talking with your parents, what do you think the difference is between saving and investing?

Based on the sources that I have read, the difference between saving and investing are these:
1. In saving, you are separating a certain sum from your income, and this sum is being kept in your personal bank account. This amount is readily available when needed anytime. 
2. In investing, you are putting your money in a certified company and you allow them to utilize it for business purposes. In investing, your money is not readily available anytime.
3. The very big difference between the two is that, in savings, the interest rate is very small, whereas in investing, you get higher returns depending on the risk appetite of the investor.
