What is the difference between a demand curve and a demand schedule?

Demand schedule:

The Demand schedule refers to the tabular representation of the quantity demanded at the various price levels. By observing the demand schedule, we can conclude that as the price of the good increases then as a result the quantity demanded for that good falls. It represents various combination of price and quantity demanded.

Demand curve:

A demand curve refers to the graphical representation of the demand schedule which shows the relationship between the price of the commodity and the quantity demanded for that commodity. It is downward sloping curve which shows that there is an inverse relationship between the price of a good and the quantity demanded.
