Computer History

The first computers were people. The earlier mechanical computers. Electronic computers were given this name because they performed the work that had previously been assigned to people. It was used to describe those human beings whose job it was to perform the repetitive calculations required to compute such things as navigational tables, tide charts, and planetary positions for astronomical almanacs. Imagine you had a job where hour after hour, day after day, you were to do nothing but compute multiplications. Boredom would leading to carelessness,quickly set in, leading to mistakes. And even on your best days you wouldn't be producing answers very fast. Therefore, inventors have been searching for hundreds of years for a way to mechanize this task.
