Описание:
Howard Aiken in collaboration with IBM, developed his first fully functional computer, known as the Harvard Mark I. The machine was huge: more than 50 feet (15 metres) long, weighing five tons, and consisting of about 750,000 separate parts, it was mostly mechanical. For input and output it used three paper-tape readers, two card readers, a card punch, and two typewriters. It took between three and six seconds to add two numbers.Добавлено на ленту времени:
