How many calculations could ENIAC perform per second?
ENIAC, one of the earliest electronic general-purpose computers, could perform approximately 5,000 calculations per second. This was a significant achievement for its time, as it dramatically increased the speed of computation compared to earlier mechanical devices. Despite its capabilities, ENIAC was still relatively slow by modern standards, as contemporary computers can perform billions of calculations per second.
How much floor did the ENIAC take up?
1,000 square feet
What is the name of the computer that in 1949 calculated an amjazing 2037 digits of pi in 70 hours?
The computer that calculated 2,037 digits of pi in 70 hours in 1949 was called the ENIAC (Electronic Numerical Integrator and Computer). This groundbreaking achievement highlighted the capabilities of early electronic computers in performing complex mathematical calculations. ENIAC was one of the first general-purpose computers and played a significant role in the development of computing technology.
Where was pi created?
π (sometimes written pi) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean spaceThe early history of π from textual sources roughly parallels the development of mathematics as a whole. Some authors divide progress into three periods: the ancient period during which π was studied geometrically, the classical era following the development of calculus in Europe around the 17th century, and the age of digital computers.Geographical Period.That the ratio of the circumference to the diameter of a circle is the same for all circles, and that it is slightly more than 3, was known to Ancient Egyptian, Babylonian, Indian and Greek geometers. The earliest known textually evidenced approximations date from around 1900 BCClassical Period.Until the second millennium, π was known to fewer than 10 decimal digits. The next major advance in π studies came with the development of infinite series and subsequently with the discovery of calculus, which in principle permit calculating π to any desired accuracy by adding sufficiently many terms. Around 1400, Madhava of Sangamagrama found the first known such series.Computer AgeThe advent of digital computers in the 20th century led to an increased rate of new π calculation records. John von Neumann et al. used ENIAC to compute 2037 digits of π in 1949
Why computers use binary language?
This is an historical question/answer.In the old days, mainframe computers (like the ENIAC) used telephone relays as computational elements, relays are electronic-magnetic switches: a magnet can be turned on by driving a current through the primary side of the relay, this magnet pulls a little switch on the secondary side of the relay from one position to another. Defining the relaxed position as zero and the attracted position as one, two values are represented.By combining multiple relays to form a larger value is an easy trick, it's like writing numbers using multiple digits:in decimal (ten-valued numbering) the number ten is represented by one ten-valued digit and zero one-valued digits:1 * ten + 0 * one = 10 = tenThis very same trick is used in binary (two-valued numbering) where the number two is represented by one two-valued digit and zero one-valued digits:1 * two + 0 * one = 10 = twoAs you can see the meaning of 10 differs by the numbering system, when we want to write ten in binary, we have to chain multiple digits together. First again in the decimal system:Hundred is represented by one ten-times-ten-valued digit, zero ten-valued digits and zero one-valued digits:1 * ten-times-ten + 0 * ten + 0 * one = 100 = hundredNote that I wrote hundred as ten-times-ten, this is the whole idea behind numbering systems!Writing hundred in binary, we needone two*two*two*two*two*two-valued (sixty-four-valued) digit,one two*two*two*two*two-valued (thirty-two-valued) digit,zero two*two*two*two-valued (sixteen-valued) digits,zero two*two*two-valued (eight-valued) digits,one two*two-valued (four-valued) digits,zero two-valued digits andzero one-valued digits:1 * sixty-four + 1 * thirty-two + 0 * sixteen + 0 * eight + 1 * four + 0 * two + 0 * one = 1100100 = hundredThis can be done easily with long division, but instead of checking how many times the value can be subtracted, you only have to check whether it can be subtracted (being either once or not at all):hundred - one-hundred-twenty-eight is less than zero (0 * one-hundred-twenty-eight)hundred - sixty-four is (equal to or) greater than zero (1 * sixty-four), remains thirty-sixthirty-six - sixty-two is (equal to or) greater than zero (1 * thirty-two), remains four... (check for every other doubling from one)Now you know how binary works, in a similar matter any other numbering system may be devised, some of the "more popular" are octal (eight-valued) and hexadecimal (sixteen-valued). Basically they are both ways to represent binary in a more readable way; each three binary digits may be grouped in one octal digit, each four binary digits may be grouped in one hexadecimal digit.Now back to why we use binary. The relay is not used a low anymore, other, more compact, alternatives are currently in use.The transistor is a small (about a match-head) device where the current flow from one point to another can be controlled by a third point, by changing the voltage on that third point. This is somewhat similar to the relay principle and is called semi-conduction; a piece of material either conducts or not depending on certain conditions (semi is a fancy name for half, so it conducts "half" the time).Combining multiple transistors in one device (getting rid of the bulky housing of each transistor) saves a lot of space. The separate transistors are so to say integrated in a single device, hence these devices are named integrated circuits or ICs.A computer contains a lot of these ICs, some of them housing over a million transistors. Yet they are still based on transistors, which are based on relays (or radiotubes, but let's not talk about these now), which can only be switch on or off. That's why we use binary.
What is ENIAC program to do?
It helps plug up but holes
What were the first three computers designed to use you a stored program?
ENIAC was the First computer that was used to store program.
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.

What was the longest operation time on the first computer?
ENIAC took ~1/3 of a second to compute a square root.
Can the ENIAC store represent and process movies or sound?
No, ENIAC could store only 20 numbers of 10 digits length. All other numbers were constants set on switches by hand. It takes thousands of numbers per second of sound and millions of numbers per second of a movie.
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.
What is first operating system or software?
The first operating system or software is widely considered to be the program ENIAC, which was created in the 1940s by the University of Pennsylvania's Moore School of Electrical Engineering. ENIAC was the first large-scale electronic general-purpose computer and was used to solve complex calculations for the US military. The program used a variety of different software components, including a control program and an arithmetic unit. ENIAC was an important milestone in the development of software and was the first program to be able to manipulate data stored in memory. It was also the first program to introduce the concept of a stored program, which allowed for faster and more efficient computing.
