ODBC identifies two types of drivers: single tier and multiple-tier.
Answer: B
Correct answer: True
ODBC does identify exactly these two kinds. A single-tier driver processes both the ODBC calls and the file access itself, which is how a driver for a simple file format such as a spreadsheet works. A multiple-tier driver passes SQL to a separate DBMS, which does the processing, and is the arrangement used for a client-server database.
