Alphanumeric

A character that is either a letter ('a' to 'z' or 'A' to 'Z') or a number ('0' to '9'). Usually this term is related to the character set being used, such as ASCII.

Alphanumeric elements are used to help define sorting orders, such as Alphabetical. They are also important when considering the way identifiers are constructed, however in that case other characters will often be permitted to separate words, for example ' ', '_', '-' or ':' depending on the implementation being used.
