B.C the abacus
The abacus is considered the oldest calculation tool, adapted and appreciated in different cultures. If the abacus hadn't invented; mankind would have created the mathematics. -
Blaise Pascal
developed a rotating gear wheels calculator, (antecedent desktop calculator), could only add and subtract, it was called the "Calculator Pascal". If Blaise Pascal hadn't invented the calculator; the scientists wouldn't have had tools for the development mathematics. -
Gottfried Leibnitz
calculator built successor to Pascal which could perform the four arithmetic operations. If Leibnitz had improved Pascal's calculator; mankind wouldn't have known the basis of mathematics. -
Charles Babbage
mathematics professor at Cambridge University created an analytical machine, considered the first computer. If Charles Babbage hadn't invented the analytical machine, the world couldn't have had computers as known nowadays. -
Herman Hollerith
a statistician design a technique to speed up the preparation and analysis of the data obtained in the census. If Herman Hollerith hadn't designed this technique, the process would have slow. -
Howard H. Aiken
was built at Harvard University, the Mark I, designed by a team headed by Howard H. Aiken. This computer took six seconds to perform a multiplication, and twelve for a division. If Mar I hadn't created, the computer would have been designed. -
John Mauchly and John Eckert
was built at the University of Pennsylvania's ENIAC (Electronic Numerical Integrator And Calculator) was the first electronic computer that ran on vacuum tubes, the design team led the engineers John Mauchly and John Eckert. This computer significantly exceeded the Mark I, and I get to 1500 times more potent. In the design of these new techniques were included computer electronics allowing minimizing the use of mechanical parts. . If the process had not changed, the activities might have been sl -
EDVAC
(Electronic Discrete Variable Automatic Computer), built at the University of Manchester, Connecticut (USA), it was the first computer with memory storage capacity. Actually EDVAC was the first true digital electronic computer history, as it is conceived in these times and since she started making more complete architectures. If the EDVAC hadn't invented, the computers wouldn't have been the sophisticated machines that are part of our daily life. -
ramac- IBM
developed the first hard drive called RAMAC. If IBM hadn't created the first hard drive, the computers wouldn't have got a success as big today. -
Digital Equipment Corporation
developed the PDP-1, the first commercial computer equipped with keyboard and monitor. If Digital Equipment Corporation hadn't created the first computer to sell, the evolution of the computer wouldn't have been so fast and so popular around the world. -
ARPANET
Intel is created and debuts the ARPANET, the forerunner of the Internet. If Intel and ARPANET had not been created, the Internet wouldn't have been the evolution of communications and the technology.
