First electronic computer

ENIAC (Electronic Numerical Integrator and Computer) was the first general purpose electronic computer. Its development began in 1943 in the United States as part of a military project. The official opening of ENIAC took place on February 15, 1946.

Some key points regarding ENIAC:

Size and weight: ENIAC occupied an entire room of about 167 square meters and weighed about 30 tons.
Technology: He used more than 17,000 vacuum tubes, about 1,500 relays, 70,000 resistors, 10,000 capacitors and 6,000 switches.
Power and performance: ENIAC could perform 5,000 additions or 300 multiplications per second. This was incredible performance for the time.

Programming: Programming the ENIAC required physical wiring connections and switch settings, making the process time-consuming and complex. However, it was capable of performing a variety of tasks, making it a general purpose computer.
Applications: ENIAC was originally developed to calculate the trajectories of artillery shells, but has also been used for research in nuclear physics, fluid dynamics and other scientific problems.
Impact: ENIAC was the first computer to demonstrate the potential of electronic computing. It served as a prototype for subsequent computers and laid the foundation for the development of the computer industry.
ENIAC marked a significant milestone in the history of computing, representing the transition from electromechanical systems to fully electronic computers. Its creation and use demonstrated how useful electronic computers could be for scientific and military applications, and stimulated the development of the computer industry in subsequent decades.
