Answers:

Control file is a binary file which records the physical structure of a database.

It includes number of log files and their respective location, Database name and timestamp when database is created, checkpoint information.

We find CONTROL_FILE parameter in initialization parameter file which stores information about control file location.

We can multiplex control files, store in different locations to make control files available even if one is corrupted.

We can also avoid the risk of single point of failure.
