+What Is an Array?
+-------------------
+
+* Definition: collection of components of the same type, stored in contiguous memory, and indexed using a discrete range
+
+* Syntax (simplified):
+
+.. container:: latex_environment small
+
+   :ada:`type <typename> is array (Index_Type) of Component_Type;`
+
+where
+
+   * :dfn:`Index_Type`
+
+      - Discrete range of values to be used to access the array components
+
+   * :dfn:`Component_Type`
+
+      - Type of values stored in the array
+      - All components are of this same type and size
+
+.. code:: Ada
+
+   type Array_T is array (0 .. 3) of Interfaces.Integer_32;
