!!! Overview
[{$pagename}] is a classification of [data] which tells the compiler or [Observer] how to use intends to use the [data]. 

Compilers or [Observers] may interpret the [{$pagename}] differently depending on the __[context]__

THere are several classifications of [{$pagename}]:
* [Primitive data type]
* [Composite data type]
* [Reference data type]

Most programming languages support various [{$pagename}]s, for example: 
Classic basic primitive types may include:
* Character (character, char);
* Integer (integer, int, short, long, byte) with a variety of precisions;
* Floating-point number (float, double, real, double precision);
* Fixed-point number (fixed) with a variety of precisions and a programmer-selected scale.
* Boolean, logical values true and false.
* Reference data types (also called a pointer or handle), a small value referring to another object's address in [memory] or a perhaps a [hyperlink]. [by-reference]

A Data type provides a set of values from which an expression (i.e. variable, function ...) may take its values. The type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored
