What does ‘dumping’ mean in computer lingo?

Dumping refers to the cleaning of stored data from the core memory area of a computer into trash or somewhere else in an unorganized manner. Dumping may be done in the event of a system failure or as part of maintenance work. The reason for dumping, in most cases, is that the data has lost its value over time and occupies huge memory space. Retrieval from the dump is difficult but not impossible.
