The Electronic Numerical Integrator and Computer (ENIAC) was the first electronic, general-purpose computer. It was designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania. ENIAC was completed in 1946 and was about the size of a large desk.
ENIAC could perform about 5,000 calculations per second. It used vacuum tubes to store data and to perform calculations. ENIAC was used to calculate artillery firing tables for the United States Army.

What did the Electronic Numerical Integrator and Computer Do?
In June of 1945, the Electronic Numerical Integrator and Computer (ENIAC) was announced to the world. The machine was the first of its kind- a general-purpose, electronic computer. It could be programmed to perform a wide variety of calculations, and it could be used to solve problems in a number of fields, including physics, engineering, and mathematics.
ENIAC was the creation of John Mauchly and J. Presper Eckert, two electrical engineers who had met as graduate students at the University of Pennsylvania. Mauchly had been working on the idea of an electronic computer since the 1930s, and Eckert had been working on the theory of electronic circuitry. In 1941, the two men founded the company ENIAC, Inc. to develop and market their new machine.
ENIAC was completed in 1945, and it was immediately put to use by the United States Army. The machine was used to calculate ballistic trajectories and to develop new weapons. In 1946, ENIAC was moved to the Ballistic Research Laboratory in Aberdeen, Maryland, where it was used to develop the hydrogen bomb.
In the late 1940s and early 1950s, ENIAC was used to calculate the orbits of artificial satellites. In 1951, it was used to calculate the trajectory of the first man-made object to orbit the Earth, the Russian satellite Sputnik.
In the 1950s and 1960s, ENIAC was used to calculate the trajectories of missiles and spacecraft. It was also used to develop the theory of nuclear weapons and to model the effects of nuclear explosions.
In the 1970s, ENIAC was used to calculate the orbits of the Voyager spacecraft.
ENIAC was a remarkable machine, and it changed the course of history. It was the first computer to use vacuum tubes, and it was the first computer to be programmable. It was also the first computer to be used for scientific calculations.
Who invented Electronic Numerical Integrator and Computer?
The Electronic Numerical Integrator and Computer (ENIAC) was the first electronic general-purpose computer, designed and built by John Mauchly and J. Presper Eckert at the University of Pennsylvania.
ENIAC was announced on February 14, 1946, and was in full operation by November of that year. The computer was unveiled to the public at the University of Pennsylvania Museum of Archaeology and Anthropology.
ENIAC was designed as a machine to solve problems in ballistics, artillery, and fire control. It could perform 5,000 operations per second, making it the fastest computer in the world at the time.
The ENIAC was a massive machine, weighing over 30,000 pounds and measuring over 8 feet tall and 80 feet long. It used vacuum tubes to perform its calculations, and required about 180,000 watts of power to operate.
The ENIAC was retired in 1955, and was replaced by more modern computers. However, the ENIAC was an important step in the development of computers, and is considered to be the first electronic computer.
What was the ENIAC used for?
The ENIAC was the first computer in the world, developed in 1946. It was used for a variety of purposes, including the calculation of artillery firing tables for the United States Army. Other early uses of the ENIAC included the development of the hydrogen bomb and the creation of the first electronic general-purpose computer.
What is the rate of Electronic Numerical Integrator and Computer?
In computing, an electronic numerical integrator and computer (ENIAC) is an early electronic computer, and one of the first machines to be able to perform the basic operations of arithmetic automatically. It was designed by John Mauchly and J. Presper Eckert during World War II and announced to the public on February 14, 1946.
ENIAC was designed to calculate artillery firing tables for the United States Army, but was soon repurposed to solve a wide range of scientific problems. The machine was able to perform 5,000 additions or subtractions per second, and could multiply two numbers at the rate of 300 per second. In its early years, ENIAC was used to solve problems such as the design of the hydrogen bomb and the orbits of planets.
ENIAC was decommissioned in 1955, and made way for more advanced computers such as the transistorized ENIAC and the UNIVAC I. However, the ENIAC’s design and principles were the basis for many of the early electronic computers, and it is still considered a milestone in the history of computing.
What are the main features of ENIAC?
The ENIAC (Electronic Numerical Integrator and Computer) was the first electronic computer, and it played a significant role in the history of computing. The main features of ENIAC were its speed, size, and ease of use.
ENIAC was much faster than the mechanical computers of the time, and it could be programmed to perform a variety of tasks. It was also much larger than earlier computers, and it required a team of people to operate it. However, it was much easier to use than earlier computers, and it could be programmed without knowing how to code.
ENIAC was developed during World War II to help with the war effort. It was used to calculate artillery trajectories and other military tasks. After the war, it was used for a variety of other purposes, including scientific research and the development of the first commercial computers. ENIAC was retired in 1955, but it has been inducted into the National Inventors Hall of Fame and the Computer History Museum.
What was the purpose of the first computer?
The first computer was created in 1876 by Charles Babbage. Its purpose was to help with the calculation of mathematical tables for the British government.
What are the limitations of ENIAC?
The Electronic Numerical Integrator and Computer (ENIAC) was the first general-purpose electronic computer, and is widely regarded as the grandfather of all modern computers. While ENIAC was a remarkable machine for its time, it had a number of limitations that would eventually be overcome by more advanced computers.
Perhaps the most significant limitation of ENIAC was its lack of memory. ENIAC could only store a single number at a time, meaning that it could not retain any data between operations. This made it difficult to perform more than a single task at a time.
ENIAC also had a very slow execution speed. It could only perform a single calculation per second, meaning that complex tasks could take hours or even days to complete.
Finally, ENIAC was very expensive to operate. Each calculation required the use of a special technician, and the machine itself consumed a large amount of electricity.
