What did von Neumann and Mauchly and Eckert invent?
One of the first functional computers, called ENIAC.
The person who contributed the idea of the stored program concept was?
Unknown. It was developed in the ENIAC project in WW2 but nobody recorded who first came up with it. ENIAC did not use it.
Who invented the concept of stored program why is this concept so important?
Nobody actually knows, except that it was being discussed on the ENIAC project before John von Neumann was introduced to the project. John von Neumann gets credit because of a distribution mistake, after he wrote the first paper on the concept. It is important because all modern computers are based on some variant of it.
What is the name of the computer that was used to calculate the ballistic course of shells during war world 2?
ENIAC. This is an acronym for Electronic Numerical Integrator And Computer. The ENIAC is Turing complete, but does not meet the generally accepted criteria for a computer because it does not have stored program capability.
Who is the father of stored program?
That cannot be determined. The idea was developed and discussed by several of the engineers working on the ENIAC design during WW2, but nobody bothered to record who first brought up the idea. The idea however was not used on ENIAC as the design was already frozen and it was necessary to build what they had if they hoped to finish it before the end of the war.John von Neumann was the first to document the idea on paper, so he is commonly erroneously given the attribution, but he definitely did not develop the idea himself.
What is the difference between eniac and edvac?
The edvac came after the eniac (its predecessor). The main difference was that with the eniac if you wanted to complete a certain process different vacuum tubes had to be tampered with, whereas with the edvac john von neumann and others realised that computers could be programmed which meant you didnt have to tamper with the hardware each time you wanted to complete a different a task.
Why is John Neumann so important to the study of computer science?
Von Neumann was a founding figure in computer science. He and Stanisław Ulam developed simulations on von Neumann's digital computers for hydrodynamic computations. He contributed to the development of the Monte Carlo method, which allowed solutions to complicated problems to be approximated using random numbers. While consulting for the Moore School of Electrical Engineering at the University of Pennsylvania on the EDVAC project, von Neumann wrote an incomplete First Draft of a Report on the EDVAC. The paper, which was widely distributed, described a computer architecture in which the data and the program are both stored in the computer's memory in the same address space. John von Neumann also consulted for the ENIAC project, when ENIAC was being modified to contain a stored program. Since the modified ENIAC was fully functional by 1948 and the EDVAC wasn't delivered to Ballistics Research Laboratory until 1949, one could argue that ENIAC was the first computer to use a stored program. John von Neumann also designed the instruction set for the modified ENIAC, and he should be given credit for this. The stored program version of ENIAC ran 6 times slower, but it was still entirely I/O bound, and programs could be developed and debugged in days rather than weeks, which is one of the advantages of having stored programs. This architecture is to this day the basis of modern computer design, unlike the earliest computers that were 'programmed' by altering the electronic circuitry. The single-memory, stored program architecture is commonly called von Neumann architecture as a result of von Neumann's paper. Stochastic computing was first introduced in a pioneering paper by von Neumann in 1953. However, the theory could not be implemented until advances in computing of the 1960s. Von Neumann also created the field of cellular automata without the aid of computers, constructing the first self-replicating automata with pencil and graph paper. The concept of a universal constructor was fleshed out in his posthumous work Theory of Self Reproducing Automata. Von Neumann proved that the most effective way of performing large-scale mining operations such as mining an entire moon or asteroid belt would be by using self-replicating machines, taking advantage of their exponential growth. Beginning in 1949, Von Neumann's design for a self-reproducing computer program is considered the world's first computer virus, and he is considered to be the theoretical father of computer virology. Donald Knuth cites von Neumann as the inventor, in 1945, of the merge sort algorithm, in which the first and second halves of an array are each sorted recursively and then merged together.

What did John Von Neumann invent?
The mathematician John Von Neumann was involved in several key projects. He was a consultant on the ENIAC (Electronic Numerical Integrator And Computer), designed and constructed at the University of Pennsylvania, which was the world's first general-purpose electronic digital computer. The major credit for the ENIAC however, is generally given to John Mauchly, a professor of electrical engineering at the University of Pennsylvania, and John Eckert, one of his graduate students. The major drawback of the ENIAC was that it had to be programmed manually by setting switches and plugging and unplugging cables. The next major advance was the stored-program concept, which is attributed to the ENIAC designers but most especially to von Neumann. The first publication of the idea was in a 1945 proposal by von Neumann for a new computer, the EDVAC (Electronic Discrete Variable Computer). The EDVAC was never built, but in 1946, von Neumann and his colleagues began the design of a new stored-program computer, referred to as the IAS computer, at the Princeton Institute for Advanced Studies. The IAS computer, although not completed until 1952, is the prototype of all subsequent general-purpose computers. So the answer to your question is that von Neumann, with help from others, invented the concept of the store-program computer and then developed (you could say invented) the IAS computer.

How many ENIAC computers were built?
1946: The Eniac Computer is UnveiledENIAC (Electrical Numerical Integrator And Calculator) was originally developed during Word War II to perform complex trajectory calculations for artillary, but the war ended before the machine was operational. But it continued to be used after the war, performing calculations for the design of the hydrogen bomb, weather prediction, cosmic-ray analysis, thermal ignition, random numbers, and wind-tunnel design. The ENIAC contained 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It covered 1,800 square feet of floor space, weighed 30 tons, and consumed 160,000 Watts of electrical power, making the lights go dim in Philadelphia each time it was powered up. On October 2, 1955 the ENIAC was shut down for the last time, but by then inventors John Mauchly and John Presper Eckert had already had the UNIVAC computer on the market for several years.
