A '''data type''' is essentially a rule for how the underlying bits of a value are interpreted. Because of this, the number of data types is practically unlimited. However, there are certain basic data types that are provided by most [[Programming language|programming languages]]. These can be grouped into boolean, numeric, string, and pointer.

A pointer represents an address in memory. This allows indirection. The memory address indicated by the pointer typically contains data of a specific type. For instance, a pointer to an integer.
