    - The following files are:

    1. Redo log files - The most crucial structure for recovery operations is the redo log, which consists of two or more preallocated files that store all changes made to the database as they occur. Every instance of an Oracle Database has an associated redo log to protect the database in case of an instance failure.

    2. Control files - A control file is a small binary file that records the physical structure of the database and includes: The database name. Names and locations of associated datafiles and online redo log files. The timestamp of the database creation.

    3. Data files - A datafile can be associated with only one tablespace and only one database.

    4. Temp files - They are a special class of data files that are associated only with temporary tablespaces.
