Detailed explanation-1: -A field type, also known as a semantic type, is the meaning of a field (or column) in a table. The field type determines how Metabase displays the field. For example, a column’s data type might be “text, ” but its field type could be “URL”. Metabase would then display the column values as links.”

Detailed explanation-2: -Think of a field’s data type as a set of qualities that applies to all the values that are contained in the field. For example, values that are stored in a Text field can contain only letters, numbers, and a limited set of punctuation characters, and a Text field can only contain a maximum of 255 characters.
