The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880 the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done‚ giving rise to punch-card based computers that took up entire rooms. Today‚ we carry more computing power on our smartphones than was available in these early models. The following brief history of computing is
