Refer to the Documentation:
http://docs.oracle.com/cd/B28359_01/server.111/b28318/startup.htm#CNCPT1295

At startup mount the control files are opened the names of the data files and redo log files are read.

These files are not opened until the database is opened.

There are three stages in the startup of a database.

At nomount, the parameter file is read, which identifies where to find the controlfiles, how to allocate memory etc.

At mount, as mentioned, the controlfiles are read and the data/redo log files are identified.

At open, the data / redo log files are opened.
