That depends on the context. In programming null is a reference to nothing, or a pointer that doesn't point anywhere. In VB the Nothing keyword is used for a null reference. In programming empty has no special meaning, it's just something that doesn't contain anything. For instance a string with the length zero. In databases null is used in fields that contains no data. Any field can contain null, unless the table specification forbids null in the field. An empty value in a database is a text field than contains no characters. A numeric field or date field can not be empty. --- b { font-weight: normal; }
