This image shows a fully loaded container ship on a clear day at sea. The difference between a container ship and a normal cargo ship is that container ships are able to carry their entire load in truck-sized containers which can be loaded and unloaded quickly onto either docks or articulated lorries who then move them inland. 

This technique is known as containerisation and means it is easier to transport commodities and goods through different freight systems without having to adapt loads or cargo. 

Bulk cargo including grain and coal would be transported in large volumes within the hull of the vessel, whereas, break-bulk cargo such as electronics and manufactured goods are transported by container.
