Understanding JDBC Internal Components

[1] In JDBC, why should we load drivers first using Class.forName ("some driver name"). Why SUN did not take care of loading the driver in the getConnection () method itself. If you pass the driver name as a parameter to the getConnection () method.

[2] I want to understand the insides of the JBDC. All landmarks are appreciated.

With JDBC 4, you will no longer need to use Class.forName (...) see here for one article explaining this:
