| dUMP |
The act of copying raw data from one place to another with little or no formatting for readability. Usually, dump refers to copying data from main memory to a display screen or a printer. Dumps are useful for diagnosing bugs. After a program fails, you can study the dump and analyze the contents of memory at the time of the failure.
