In computers, dump means "dump" in Chinese, which generally refers to the export and transfer of data to a file or static form, that is, dynamic (volatile) data is saved as static data (persistent data). Dump is not necessary for data such as programs that are already stored in a storage medium (such as a hard disk).

The operating environment of this tutorial: windows7 system, Dell G3 computer.

1. Why dump

Generally refers to the export, transfer of data to a file or static form. For example, it can be understood as: the contents of memory at a certain time, dump (rollover, export, save) into a file.

Because when the program is running in the computer, the data on memory, CPU, Imax O and other devices are dynamic (or volatile), that is to say, when the data is used up or an exception occurs, it will be lost. If I want to get data at some point (possibly a debugger Bug or collect some information), I have to dump it in the form of a static (such as a file). Otherwise, you'll never get the data.

2. What is dumped by dump

Is to save dynamic (volatile) data as static data (persistent data). There is no need for dump for data such as programs that are already stored in a storage medium (such as a hard disk).

Now, it is easy to understand dump as a noun, which generally refers to the file or static form obtained in the above process. It refers to the result file of dump (verb).

There are common dump scenarios: headdump and threaddump in coredump,Java in Unix/Linux, as well as tcpdump tools.
