answer:A memory dump is when a computer records all of its internal memory (RAM and registers) to permanent storage (ROM). This gives a snapshot of everything that is happening in a computer at a single point in time, allowing it to possibly shut down and restart as if nothing has happened. One use of core dumps is to debug software. It acts sort of like a black box, telling the programmer exactly what was happening when a program crashed. Another use is for restoring a user session after a device’s battery dies. When my laptop dies, Windows dumps its memory. When the computer is eventually restarted, Windows can resume, and all of the running programs are restarted and it’s as if nothing happened. As for what a dump file is, I would assume it is where the operating system stores the memory dump. For some additional sources, you can look up “core dump” on Wikipedia.
