The work done by Bell Labs was broadly divided into three categories: research, systems engineering, and development. Research created the theoretical underpinnings for telecommunications. It covered subjects such as mathematics, physics, material sciences, behavioral sciences, and computer programming theory. Systems engineering concerned itself with conceiving the highly complex systems that make up the telecommunication networks. Development, by far the largest of Bell Labs' activities designed the specific systems -- both hardware and software -- needed to build the Bell Sy ...
