Difference between JDBC Driver type numbers

Question

I noticed that JDBC has different Drivers like:

1. Type 1 Driver
2. Type 2 Driver etc.. to Type 4

Why did they get the name like Type 1, Typ

Answer 1

Does not seem to be any logic, just plain laziness I guess!

UPDATE: The question was whether there was some logic to calling it type 1, type 2 etc instead of calling type apple, type orange :). I understand that the driver types are different and work/not work based on circumstances, but why the name "Type 1" instead of "Type JDBC-ODBC" or "Type JO" has no reason AFAIK.
