A coral reef is a community of organisms that exist in shallower ocean depths. The key component is coral, which often forms the foundation of the reef ecosystem. Coral species may either be photosynthetic or non-photosynthetic, however, the foundational species as well as the predominant majority are often photosynthetic.

Most people define a 'reef' as a 'coral reef', but there are however manmade reefs, often called artificial reefs. These reefs are usually made from scrap material such as bridge rubble, or sunken ships. I would also call underwater rock formations that are often inhabited by various marine species a type of reef as well.

What are the difference of corals and coral reefs?

A coral reef is a colony of corals. A coral reef can be formed on rock rubble, but old established coral reefs are actually structured out of dead coral. This is one of the reasons it takes so long for a reef to form. Some corals may life for tens or even hundreds of years before they die and allow another coral to grow on top of their skeleton. There are many types of coral reefs, but the real difference is that coral is what makes up a coral reef.
