“Dump”. This is one of the most cliché words I’ve heard among hardcore programmers and hackers, and yet, I never knew what it means. I found it almost everywhere that center around low-level software and digital hardware. They say something like “dumping a file”, “dump a CPU”, “dump a memory”, and so on. What is it, and how is this feat usually performed?

A dump is data taken from a storage medium, AS-IS, i.e. unedited.
For example, core dump is a the content of the recorded state of the core from a specified time.
In Unix, Dump is a software to backup file systems.
In essence, dump is a content taken from a storage medium (that contains the all state of the medium), that is used mostly for debugging purposes.
