one.What elements must include the hardware in an embedded system? Is it different than what is needed on a desktop system? 2. Briefly describe what the following terms mean: (a) SOC, (b) PBC, (c) SBC, (d) Shield. Give an example of each. 3. What are the differences between a microcontroller and a microprocessor? Justify it. Four. What essential differences are there between a Raspberry PI platform in an SBC with respect to the industrial version of it? Justify the answer. 5. For the development of an embedded system, a hardware platform is required that has an ARMbased microprocessor, a fixed RAM memory of 256Kb and a FLASH memory of 2Mb. The manufacturer has in its catalog two solutions equal to those that the developer is looking for, but one has a double flash than the other for 2.4 more. The program fits perfectly in the provided flash memory, and runs fine with the specified RAM, but a larger FLASH memory might allow more data to be incorporated. What should you do, which one should you buy better? Justify the
