Random Access Memory (RAM)is used for storing information such as machine code and working data. It is like theshort-term memoryof a computer, where theinformation gets erased when you shut down the computer. As data is accessed randomly instead of sequentially,RAM is very fast. Hard Drive ...
ENIAC (Electronic Numerical Integrator And Computer) was the world's firstgeneral-purpose electronic computer. ENIAC is also considered the world's first programmable computer, although programming the computer was a complex, manual process that could take days. Even so, ENIAC was 1,000 times faste...
Data centers date back to the 1940s. The US military's Electrical Numerical Integrator and Computer (ENIAC), completed in 1945 at the University of Pennsylvania, is an early example of a data center that required dedicated space to house its massive machines. Over the years, computers became ...

The picture is a public domain U.S. Army photo of the ENIAC. The wires, switches, and components are all part of the ENIAC with two of the team of operators helping run the machine. The ENIAC is now displayed at the Smithsonian Institution in Washington D.C. In 1996, the U.S. ...
'A Pretence of What is Not'? A Study of Simulation(s) from the ENIAC PerspectiveA pretence of what is not"? Eine Untersuchung von Simulation(en) aus der ENIAC-Perspektive What is the significance of high-speed computation for the sciences? How far does it result in a practice of ...
ENIAC was designed to be a modular computer to be composed of individual panels that perform separate functions, and it was the first large-scale computer to run solely on electronic components without any mechanical parts slowing it down. Because of its design and 100 kHz clock, it could do...
John Mauchly and J. Presper Eckert (1945) designed and built theElectronic Numerical Integrator and Computer(ENIAC), one of the earliest electronic general-purpose digital computers. ENIAC could be reprogrammed to solve a wide range of numerical problems. ...
用药差错，又称用药错误，是指药品在临床使用及管理全过程中出现的，任何()的用药疏失可导致患者发生潜在的或直接损害（）
this paper revisits the roots of computer simulation in the development of the ENIAC computer and the Monte Carlo method.With the aim of identifying more clearly what really changed (or not) in the history of science in the 1940s and 1950s due to the computer, Iwill emphasize the continuiti...
