# Elementary Data Types (Visual Basic)

Visual Basic supplies a set of predefined data types, which you can use for many of your programming elements. This section describes these types and how to use them.

Note

Every elementary data type in Visual Basic is supported by a structure or a class that is in the System namespace. The compiler uses each data type keyword as an alias for the underlying structure or class. For example, declaring a variable by using the reserved word Byte is the same as declaring it by using the fully qualified structure name System.Byte.
