Numerous old parts used in machines have stood the test of time. When the part malfunctions or breaks down completely, you replace the component, not the whole device. A process known as reverse engineering makes replacing these parts possible. In any given factory or office building, you’re likely to see manufacturing or computing systems comprised of sophisticated equipment. Typically, the parts in question will range in age from new to more than 20 years old. For these systems to remain intact, various components must be reverse engineered and recreated.
