 # Terms and definitions
 
-**Data type** - A field type with its associated encoding attributes,
+**datatype** - A field type with its associated encoding attributes,
 including backing primitive types and valid values or range. Some types
 have additional attributes, e.g. epoch of a date.
 
 **Encoding** - a message format for interchange. The term is commonly used
 to mean the conversion of one data format to another, such as text to
 binary. However, Simple Binary Encoding strives to use native binary
-data types in order to make conversion unnecessary, or at least trivial.
+datatypes in order to make conversion unnecessary, or at least trivial.
 Encoding also refers to the act of formatting a message, as opposed to
 decoding.
