This article is about volcanic calderas. There is also a corporation called Caldera Systems.
A caldera is a volcanic crater which usually has a flat surface at the bottom, formed by a volcano collapsing into itself, usually because of low pressure in the magma chamber below or because of a violent eruption.
An example of a caldera is in Crater Lake National Park. The caldera on Mt. Mazama has filled with water, creating Crater Lake.
