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 engineers generally specialize in one of three disciplines: computer hardware systems, computer systemsâ software or computer software applications. Those who specialize in computer software are often referred to as software developers or engineers and in many cases, work closely with computer hardware engineers. These professionals design computers and their software, then oversee the development of their designs from conception to completion.
