An image copy is an exact copy of a single datafiles, archived redo log file or control file.

MP3, AIF (Audio Interchange File), and WAV are all digital audio file formats for storing sound. COM is a file extension for DOS executable programs (commands), not audio files. Other audio extensions include MP3, WAV, WMA, AAC, FLAC, OGG, and AIFF.

JPEG, GIF, and BMP are all image file formats used for storing pictures and graphics. TMP is a generic extension for temporary files that can contain any type of data - it's not specific to images. Temporary files are used by programs to store data temporarily during processing.

Exit is not a valid AWK variable.

The write permission allows the user to write or edit the contents of the file.

A file handle is a unique identifier that an operating system assigns when a file is opened. Programs use this handle to reference and manipulate the open file throughout its execution. Each open file gets a distinct handle to track file operations.

FAT stands for File Allocation Table, a file system architecture developed by Microsoft for MS-DOS and later used in Windows. It keeps track of how files are stored on the disk. The question has a typo ('satnds' instead of 'stands') but this doesn't affect the answer. Option C is correct.

A tablespace can have many data files associated with it.

FTP opens a new data connection for each file transfer operation during a session. The control connection stays open, but data connections are created and closed as needed for each transfer.
