On February 15th, 2022, symposiums are held to discuss the first computer historical significance, computer architecture evolution, and six women who worked as its programmers, but only recently received well-deserved recognition.
World Computer Day is an annual celebration of computers and people who create IT. This year, World Computer Day can be celebrated for many reasons. There is nothing more important than celebrating the revolutionary 6502 chip; chip that changed the world!
It is explained that ENIAC used plugboards to relay instructions to the machine. This had the advantage that once instructions were thus programmed, machine ran at electronic speed. Instructions read from a card reader or other slow mechanical device would not be able to keep up with all-electronic ENIAC. The disadvantage was that it took several days to change the machine to solve each new problem, and this was a problem.
Every year - a new theme, new events, new resources and new friends! Last year, on February 15th, 2021, we celebrated ENIAC on World Computer Day; 75th Anniversary of the world first all-electronic programmable computer ENIAC on ENIACDay.org website. Take your time, look around and find out everything there is to know about celebrating World Computer Day on February 15th every year. We hope you enjoy your holiday!
Yes, we know that it actually started in 1945, not February 15th, 1946, but today, 75 years ago, machine was launched at the University of Pennsylvania. In 2011, the Philadelphia City Council declared February 15th ENIAC Day, and we are not going to argue with that opinion. While Blythey pundits might point to the top-secret Colossus as a precursor to ENIAC, the launch of this general purpose computer was a very public affair. Conceived as an improvement on the wheel-and-disk differential analyzers of the day, work on electronic machine began in secret in 1943.
The first iteration was completed by the end of 1945, and the jump in performance from what had been in the past was spectacular. The 680-square-foot, 30-ton computer was capable of performing ballistic calculations that could previously take 12 hours in just 30 seconds. Not surprisingly, he spent most of his service life as the main computing engine for US Army.
In addition to ballistic trajectories, it has also been used in solving atomic energy problems for Manhattan Project and in a design of wind tunnels. The statistics are astonishing for those who are accustomed to the compact and low-power systems of recent years. ENIAC had its own power lines and consumed electricity in 150 kW.
Before the era of microprocessors, it consisted of 40 panels 9 feet high and 2 feet wide, arranged in a U shape, and required 18,000 vacuum tubes, half a million solder joints, 70,000 resistors, and 10,000 capacitors. It also had to be manually programmed for each new set of calculations, a lengthy task involving setting up switches and cables. Debugging involved stepping through programs one instruction at the time. The technician carried a manual box with a button that allowed the computer to move on to the next step, and result was compared to a human calculation. Changes were made in 1948 to add program storage capability to greatly relieve pain, and in 1953 the Burroughs Corporation installed a hundred-word magnetic core central memory unit. However, by 1955, the writing was on the wall as advances in computing made ENIAC obsolete, and the beast was finally shut down. Today, computer components can be found in museums around the world, such as London Science Museum. Other components can be found at University of Pennsylvania and Computer History Museum in Mountain View, California.
Between 2019 and 2022, open source developers solved Linux problems in an average of 25 days, compared to 83 days for Microsoft and Oracle, who fell into last place at 109 days. Although due to a very small number of cases. In addition, Linux has shown a continuous improvement in response time from 32 days in 2019 to just 15 days last year, and this improvement is reflected across the industry.
So please join us in raising a toast to ENIAC and the debt owed to it by modern computers. ENIAC history is well documented, but Kevin Ritchie book ENIAC is recommended for lunchtime reading, as well as an article in Penn Engineering History and Legacy section. These figures do not always match. Ritchie lists 42 panels and more than 19,000 vacuum tubes, while Penn, for example, says 40 and 18,000, but both give an idea of its scope.
