| The Stored Program Computer | |
| In the late 1940's, John
von Neumann considered the idea of storing computer instructions in a central
processing unit, now known as the CPU.
Together with Mauchly and Eckert, von Neumann designed and built the EDVAC & EDSAC (Electronic Discrete Variable/Storage Automatic Computer). With this development of programs, the modern computer age was ready to begin. Next was the UNIVAC Universal Automatic Computer (made by Mauchly and Eckert) which sold to the U.S. Census Bureau in 1951. It weighed 35 tons, did 1000 calculations per second, and was very expensive to purchase and run, so only the largest corporations and the U.S. Government could buy the UNIVAC. |
