Originally, the term of "computer" referred to a person who performed numercial calculations often with the aid of a mechanical calculating device. Examples of early mechanical computing devices included the abacus, in 1623 Wilhelm Shickard Built the first mechanical calculator and thus became the father of the computing era, but none of those devices fit the modern definition of a computer, because they could not be programmed In the future, computing devices began to develop faster and faster, and already in 1941, the German scientist Konrad Zuse designed the first working and programmable computer. In the 1950s and 1960s, computers were only available to large companies due to their size and cost, but due to competition, companies sought to reduce designs and minimize the cost of manufacturing personal computers. In the USSR there are also several computer inventors. In 1948 Bruk and in 1950 Ledev together with other scientist showed their ECM. |
