The whole point of a computer is to perform mathematical computations. In the year Jacquard Loom devised a punch card system with a power loom and an automatic card reader. In , Gottfried Wilhelm von Leibniz invented a computer that was built in ; it could add and, by successive adding and shifting, multiply. Leibniz invented a special "stepped gear" mechanism for introducing the addend digits, and this mechanism is still in use. The prototypes built by Leibniz and Pascal were not widely used but remained curiosities until more than a century later, when Tomas of Colmar Charles Xavier Thomas developed the first commercially successful mechanical calculator that could add, subtract, multiply, and divide.

The History of Computers To those of us that have grown up during the computer age, computers seem like a normal part of our everyday lives. The idea that only a few decades ago computers were virtually unheard of is inconceivable. Computers are now so essential that they basically run our society and the whole of the modern world. They track hurricanes, forecast the weather, predict natural disasters, control satellites and missiles and keep countries around the world in constant contact. Many historians give the credit to the American scientists J.
Evolution of Computers Essay
The abacus was an early aid for mathematical computations. Its only value is that it aids the memory of the human performing the calculation. A skilled abacus operator can work on addition and subtraction problems at the speed of a person equipped with a hand calculator.
The computer was able to store tons more date in was less space. The magnetic tape worked in the same way that a music or audiotape worked. The small compact design and tons of tape rolled into the small plastic tons of bites of data could be stored. This was revolutionary for the computer improving many aspects like size, weight, efficiency, and speed.
