Involvement of the lung causes shortness of breath or fatigue during physical activity. Many patients with scleroderma become less physically active because of musculoskeletal complaints or the fatiguing nature of the illness. Hence many will not be physically active enough to actually develop shortness of breath.
Computer hardware engineers research, design, develop, and test computer systems and components such as processors, circuit boards, memory devices, networks, and routers. These engineers discover new directions in computer hardware, which generate rapid advances in computer technology.
Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to develop computer hardware and software.omputer software engineers can also work in application design. This involves designing or coding new programs and applications to meet the needs of a business or individual. Computer software engineers can also work as freelancers and sell their software products/applications to an enterprise/individual.
