| The handheld computing device attests to the remarkable miniaturization of computer hardware. The early computers of the 1940s were so large that they filled entire rooms. Techonological innovations, such as the integrated circuit in 1959 and the microprocessor in 1971, shrank computers’ central processing units to the size of tiny silicon chips. Handheld computers are sometimes called personal digital assistants (PDAs). | ||||||
