What is the difference between short-circuit and overloading?

The differences between short-circuiting and overloading are: 

Short-circuiting Overloading
Short-circuiting happens when a live wire comes in contact with a neutral wire. Overloading happens when the amount of current drawn by a source exceeds the amount of current that a source can supply.
At the point of short-circuit, the potential difference falls to zero. Potential difference assumes non-zero but a very low value in overloading.
The current flow is high at the time of short-circuiting. During overloading, the flow of current is lower than the flow at the time of shortcircuiting.
