Final answer:
The shift toward mobility in computing is driven by advancements in nanotechnology and miniaturization, leading to devices like the iPhone. It is further supported by the transition to an information economy, the effects of Moore's Law, and the use of computers to design even more powerful computers.
Step-by-step explanation:
The shift toward mobility in computing can be attributed to several pivotal developments and trends. Firstly, the significant progress in nanotechnology and miniaturization has made it possible for computers to become small enough to be integrated into everyday personal devices. Devices such as smartphones, exemplified by the iPhone, have brought worldwide communications into the hands of many, including those in rural areas previously lacking phone systems. Furthermore, the advent of the information economy has played a crucial role. There has been a move away from manufacturing to service industries, coupled with the globalization of the economy. This shift has been further bolstered by the exponential growth described by Moore's Law, which has seen the capabilities of electronics rapidly double every two years, enabling more potent and energy-efficient computing devices.
Lastly, the positive feedback loop generated by using computers to design more advanced computers has accelerated technological advancement. Together with the change in workforce dynamics from active work to service industries, these factors have greatly contributed to the enhancement of mobile computing options, catering to a more digitized and networked global society.
