The Electronic Numerical Integrator and Computer (ENIAC) stands as a landmark in the history of computing, marking the advent of electronic general-purpose computers. Developed at the University of Pennsylvania (UPenn) in the 1940s, the ENIAC computer not only pushed the boundaries of computation but also laid the foundation for modern computing. In this blog post, we will delve into the technical details and specific examples of takeaways from the work at UPenn.
Background
During World War II, there was a pressing need for advanced computing capabilities for military calculations. In response, the United States Army initiated a project at UPenn to develop a high-speed electronic digital computer. The result was the ENIAC, which was the world’s first general-purpose electronic computer and a significant leap forward from the earlier electromechanical machines.
Technical Specifications
The ENIAC computer was a behemoth of its time, spanning an entire room and comprising thousands of vacuum tubes, resistors, capacitors, and other electronic components. Here are some notable technical specifications of the ENIAC:
- Size: The ENIAC occupied a floor space of about 1,500 square feet (140 square meters).
- Weight: It weighed approximately 30 short tons (27 tonnes).
- Power Consumption: The ENIAC consumed around 150 kilowatts of electricity.
- Vacuum Tubes: It employed over 17,000 vacuum tubes, which were responsible for performing calculations.
- Programmability: The ENIAC was reprogrammable, allowing it to solve a wide range of computational problems.
Key Takeaways from the Work at UPenn
