What is the difference between exhaust fan and ceiling fan?

What is the difference between natural ventilation and power exhaust?
While natural ventilation relies on the laws of nature to create airflow, power exhaust creates airflow by forcing air out using exhaust fans. These fans suck the air out of the top of the building while fresh air is sucked into the building through vents in the wall.
How does an exhaust fan work?
Exhaust fans work by sucking hot or humid air out of a small, localised area, allowing fresh air to enter from elsewhere (perhaps a doorway or vent) in order to replace it. The warm air that's drawn out using an exhaust fan is then pulled through a ducting system and expelled outside.
Does exhaust fan help in ventilation?
When it's installed high up, it will exhaust the hot air and improve the ventilation in a room. This will ensure that you get cooler air in all rooms of the house. For large rooms, you should consider buying large exhaust fans so that it can get rid of warm air faster.
When would you use a ventilation fan?

What are the different types of exhaust fan?
There are two main types of exhaust fans:Axial Fans: These fans look like propellers and draw air straight through the fan.Centrifugal fans: These fans look like "squirrel cages" that draw air into the centre of the fan and exhaust it at a 90-degree angle.
What are the three types of ventilation?

When one uses an exhaust fan what kind of heat transfer is demonstrated?
Convection: Convection is the transfer of heat from a surface by means of a fluid such as air. Natural convection occurs as air is heated: it expands, rises, and is replaced by cooler air. The amount of convection may be increased by using a fan to increase the flow of air.
