Two characteristics of the ENIAC computer

The ENIAC (Electronic Numerical Integrator and Computer), sometimes referred to as the first generation of computers, had unique features that characterized its use and functioning at the time.

  1. High Power Consumption: The ENIAC was notorious for its exceptionally high power consumption. It required a significant amount of electrical power to operate efficiently. This characteristic stemmed from its use of vacuum tubes, which consumed substantial electrical energy to power and cool the system.
  2. High Heat Generation: Due to its reliance on vacuum tube technology, the ENIAC generated substantial amounts of heat during its operation. The vacuum tubes were a crucial component of the ENIAC’s circuitry and computing process. However they were known for their tendency to heat up rapidly during use, necessitating cooling mechanisms to maintain the system’s functionality and prevent overheating.
  3. Machine Language Operation: The ENIAC operates primarily using machine language, the lowest level of programming language that directly communicates with the computer’s hardware. Programs for the ENIAC had to be meticulously designed and translated into machine language to enable the computer to execute tasks. This made programming a labor-intensive and time-consuming process as it involved physically configuring the machine’s wiring and switches to perform the desired calculations.

ENIAC had memory

The ENIAC once cutting-edge now possesses a mere 20 words of electronic accumulator-based internal memory. This severe limitation restricts the complexity of tasks without frequently relying on external punched-card memory.

The ENIAC computer’s speed

The Electronic Numerical Integrator and Computer (ENIAC) was a groundbreaking electronic computer that operated at an impressive speed during its time. It could perform approximately 50 multiplications or 5,000 additions in a single second. This remarkable performance was achieved through a clock running at a frequency of 100,000 cycles per second, or 100 kHz.

One notable aspect of ENIAC’s operation was its method of programming. Unlike modern computers with software-based programming, ENIAC’s programming was accomplished through physical means. Programmers had to manually configure the computer’s operations by moving switches on a “plugboard.” This plugboard akin to a complex switchboard allowed for the setting of specific instructions and configurations necessary for each computational task.

Retiring ENIAC

In the years following World War II, the Electronic Numerical Integrator and Computer (ENIAC), a groundbreaking electronic general-purpose computer played a pivotal role in advancing various research endeavors. Originally developed for military calculations during the war, ENIAC’s potential for broader application became evident. As a result the U.S. Army recognizing the transformative potential of ENIAC beyond military operations provided universities with free access to the machine for a range of civil research projects.

This gesture by the Army marked a significant turning point as academic institutions gained unprecedented access to state of the art computing capabilities. The universities utilized ENIAC for a diverse array of research projects spanning mathematics, physics, engineering and other scientific disciplines. The computer’s immense computational power allowed researchers to tackle complex problems and accelerate their investigations, opening new horizons for academic and technological progress.
