methods. Usually, engineers would prefer non-destructive preventative methods because they allow for larger firms to save money. Many engineers, and engineering firms, use simulation software to design products make it likely that it will function properly in the real world [3]. These software are non-destructive, and allow engineers to predict how a product will operate. The downside to using simulation software to prevent product failure is that they can be time consuming. Some computer architectures are very complex

and require many operations. Because of this, simulations can be very tedious and time consuming in performing all the functionalities of a CPU, or other complex systems [4]. Destructive preventative methods are not very common in the field of microprocessors, because they would cause way too much money loss for large corporations. Before simulation technology, engineers would use destructive preventative methods. They would build a product, and simply test it. If it did not work, then they would waste the parts, which costs money, and would lose the time they spent on building the device. Due the popularity and efficiency of simulation software, many people and corporations do not use destructive preventative methods. Forensic Methods Like preventative methods, forensic methods consist of destructive and non-destructive forensic methods. They are used to diagnose a product and look deeper into the functionalities of a system. An example of a forensic method is the “Mobile Device Tool Classification System,” shown in Figure 2[5].

Figure 2: Mobile Device Tool Classification System [5] As shown by the figure, one of the steps in the Mobile Device Tool Classification System is manual extraction. This is would be considered a destructive forensic method because it requires for engineers to open up the product and see the parts of the electrical device. This procedure can become

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
