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.
Engineers often work on teams and must be able to communicate with other types of engineers as well as with non-technical team members. Computer hardware engineers ensure that computer hardware components work together with the latest software developments. Therefore, they sometimes work with software developers. For example, computer hardware engineers give developers of mobile applications information about what kind of software a cell phone can run.
