Reverse engineering is the process of discovering the technological principles of a device, object, or system through analysis of its structure, function, and operation. It often involves disassembling something (a mechanical device, electronic component, computer program, or biological, chemical, or organic matter) and analyzing its components and workings in detail - for either purposes of maintenance or to support creation of a new device or program that does the same thing, without using or simply duplicating (without understanding) the original.
