Sun defines four JDBC driver types.
Answer: B
Correct answer: True
Sun defines four: Type 1, the JDBC-ODBC bridge; Type 2, calling the DBMS’s native client library; Type 3, speaking to middleware over a network; and Type 4, pure Java speaking the DBMS protocol directly. The four differ in how much native code they require and hence in where they can be deployed.
