John put Liu mosh Valley (John W. Mauchly) and J. press per an born business (J.Prespern Eckert) funded by the United States Army in the creation ENIAC calculator when years 1946 is "The world's first electronic calculator machine Or the computer of the world's first "
.ENIAC is an abbreviation of Electronics Numerical Integrator and Computer a calculator with a purpose to use in the army. Using the calculated table to fire the cannon. The artillery. Using vacuum tubes, the 18 000 tube have fully developed 30 tons. Space, room 15000 square foot work time to take up 140. Calculation in digital system, this ENIAC mosh Valley, the concept from the machine. ABC of Atacama with his
.The size of the air ENIAC is the large square Two orders of magnitude) compared to the computer with the current production. It also works much slower computers, more than 100000 times (Five orders of magnitude) by the positive, 1900 times per minute. ENIAC chipsets Conditional Jump and can program. Which is obvious difference compared with the calculator in the same era. Programming by the plug wires, extensionThe input is done by use of punch cards. Programming each time it takes half an hour to the day since the machine is ENIAC computers can use variety. But the limitation of memory.In 1944 John von Neumann get persuasion to join the project ENIAC period, a group of researchers who are talking. How to improve writing and packing. The program into the machine and the concept of Store Program.John von Neumann took such ideas to crystallize, writing and recording, the concept of Store Program called EDVAC (Electronic Discrete. Variable Automatic Computer), then Herman Goldstine distribution record by the name of the John von Neumann only one name. Do not put the name of the J.And Presper Eckert John Mauchly with main part in the work. These records is the origin of the word von Neumann Computer pioneer in the line of academic computer was born that distribution of these records."Von Neumann Computer 'is an honor J.And Presper Eckert John Mauchly an engineer is a main part in the project ENIAC too little and is an honor John von Neumann. Too much
.In 1946 Maurice Wilkes University Cambridge come visit and Moore School attend the lecture series เรื่องการพัฒนา of electronics computer. When Maurice returned to Cambridge Wilkes.EDSAC (Electronic Delay Storage Automatic Calculator) in 1949 machine EDSAC begin to use, and a computer. Perfect in a manner that is a full computer work and the ำงานแบบ Store-Program
