计算机技术的第一次出现在美国的1…
One of the first occurrences of computer technology occurred in the USA in the 1880s. It
was due to the American Constitution demanding that a survey is undertaken every 10 years.
As the population in the USA increased, it took an increasing amount of time to produce the
statistics. By the 1880s, it looked likely that the 1880 survey would not be complete until
1890. To overcome this, Herman Hollerith (who worked for the Government) devised a machine
which accepted punch cards with information on them. These cards allowed a current
to pass through a hole when there was a hole present.
