It weighed 30 tons and occupied 1,800 square feet of floor space.<\/p>\n<p>The ENIAC could perform 5,000 additions or subtractions per second, or 35 multiplications or divisions per second. It could also perform trigonometric and logarithmic functions.<\/p>\n<p>The ENIAC did not store programs in its internal memory. Instead, it was programmed by plugging and unplugging cables. This made it very difficult to program and change programs.<\/p>\n<p>The ENIAC was a revolutionary machine, but it was soon replaced by more advanced computers. The first computer to store programs in its internal memory was the EDVAC (Electronic Discrete Variable Automatic Computer), which was built in 1949.<\/p>\n<p>The EDVAC was a major improvement over the ENIAC. It was much faster and could be programmed much more easily. The EDVAC was the first computer to use the stored program principle, which is the basis for all modern computers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[727],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The first electronic general purpose digital computer built by Mauchly and Eckert called ENIAC did not work on the stored program principle.
