Which country invented the computer?

Question 1: Which country did the computer originate from and who invented it? What would the world be like if there were no computers in America? 1946 On February 4th, the first modern electronic computer "ENIAC" was born. Today, the computer is 60 years old. Choosing such a special day as "Valentine's Day" to unveil the mystery is whether the relevant parties anticipated that this behemoth of "dimming the lights of the whole city after use" would become the new favorite of mankind and deliberately did it, or whether it was unintentional and impossible to verify. It is an indisputable fact that after 60 years of changes, the offspring of this 1946 "Valentine's Day Special Gift", which we call "computer" vividly, has penetrated into every corner of the world and even become the best "lover" around many people. February 1946, 14, at Moore School of Electrical Engineering, University of Pennsylvania, there was a festive atmosphere everywhere. Many guests come here with excitement because they will attend the unveiling ceremony of the first modern electronic computer in human history. What is presented to people is a strange-looking and glowing monster. It is the world's first modern electronic computer "ENI-AC". At the unveiling ceremony, "Eniac" performed its "unique trick" for the guests-completing 5000 addition operations and 500 multiplication operations in 1 second respectively, which was more than 1000 times faster than the fastest relay computer at that time. This perfect appearance made the guests applaud. However, who knows, in the process of the birth of this behemoth, how many people have devoted countless efforts to it!

Question 2: Which country first invented the real computer? 1946 was born in America?

The original meaning of computer is "calculator", that is to say, human beings will invent computers with the initial purpose of helping to deal with complex digital operations. The concept of manual calculator can be traced back to Pascal, a great French thinker in the 7th century. Pascal's father is the tax director. At that time, the monetary system was not decimal, so it was very troublesome to calculate. Pascal used the gear principle to assist his father and invented the first calculator that can add and subtract. Later, the German mathematician Leibniz improved it and invented a calculator that can do multiplication and division. After that, although the function of the calculator was improved and refined, the real electric calculator could not be manufactured until AD 1944.

The first machine that can really be called a computer was born in the United States in 1946. It was invented by Mao Qili and eckert, and its name is ENIAC. This computer uses vacuum tubes to process signals, so it is huge (occupying one room) and consumes high power (everyone in the town knows when to use it, because the lights in every household are dimmed! ), and the memory capacity is very low (only 100 words), but it is already a great progress in human science and technology. And we usually call this kind of computer using vacuum tube the first generation computer.

Question 3: Who invented the earliest computer? Which country is it? What time? The first electronic computer was made shortly after the Second World War. At that time, with the development of artillery, trajectory calculation became more and more complicated, and some original computers could not meet the requirements of use, so a new fast calculation tool was urgently needed. In this way, with the efforts of some scientists and engineers, on the basis that electronic technology has shown the functions of counting, calculation, transmission and storage control, electronic computers have emerged. The first electronic computer in the world was named Eniac, which was successfully developed by eckert and others of the University of Pennsylvania in 1946. It is equipped with more than 18 000 electron tubes and a large number of resistors and capacitors, and it has been operated by electronic circuits for the first time. Eniac can do 5000 additions or 400 multiplications per second. If the 40-point trajectory was calculated by the fastest electromechanical computer at that time, it would take two hours, while Eniac only took three seconds, which was really a great achievement at that time. However, Eniac is not perfect. In fact, it has no memory, only a register made of electron tubes, which can only store 10 bits. When other topics need to be changed, it is time-consuming to re-weld the connection.

Question 4: Which country in the United States invented the computer? (Reply to two words, the system is too simple, that is, the United States of America)

Question 5: In which country was the computer first invented? Ha ha! ! I hope my following answer can satisfy the landlord! Thank you for your support! ! Uh huh! There are two answers: the first one: 1940, Walter? Aiken made the first new computer and named it "Mark 1". This computer is huge and noisy, and can only handle two extra problems per second, but it is the earliest computer after all. The second type: 1946 was invented in Moore College of Pennsylvania State University in February, USA, and its name was ENIAC, which was mainly composed of Professor Mockley and his doctoral student eckert. This computer uses vacuum tubes to process signals, so it is huge (occupying one room) and consumes high power (everyone in the town knows when to use it, because the lights in every household are dimmed! ), and the memory capacity is very low (only 100 words), but it is already a great progress in human science and technology. And we usually call this kind of computer using vacuum tube the first generation computer. The first generation computers were as big as two classrooms and much smaller than the personal computers we usually use now. At that time, the computer part was a vacuum tube (now I can't find it), and what was archived was punch cards. Without the previous design concept, there would be no invention of computers! ! Haha, I hope my answer will satisfy the landlord! ! Thank you for your support! !

Question 6: Who invented the notebook computer? What country are you from? The inventor of the first notebook computer was not Toshiba, nor Apple or IBM, but a company called "Osborne Computer", whose founder was Adam? Adam Orn.

1981April, Osborne Company invented the world's first notebook computer, and Adam, the founder of Osborne Company, led the research and development. Osborne used to be a journalist, but later he abandoned his pen and went into business. Once upon a time, Osborne was considered to be with Microsoft founder Bill? Bill Gates and Apple founder Steve? Steve Jobs is equal. Osborne Computer Company is also the fastest growing company in the history of Silicon Valley. However, due to the advanced concept, the company fell apart in less than 30 months of operation. Osborne made many wrong promises in technology, and the product release date is far away. Now the industry calls this situation "Osborne effect".

As the first notebook computer in the world, Osborne 1 weighs 20 kilograms and has no battery, so it is not portable at all according to the present eyes. However, compared with the personal computer that was a giant at that time, the Osborne 1 model was much smaller, and people could put it in a box and carry it with them. In addition, Osborne 1 was the first computer with practical software, which was surprisingly cheap at that time, as long as 1795 dollars.

Question 7: Which country invented the computer? What was it originally used for? The birth of man's first electronic computer

ENIAC1946 On February 15, the world's first universal electronic digital computer "ENIAC" was successfully developed. The success of "Eniac" is not only a monument in the history of computer development, but also a new starting point for human beings in the process of developing computing technology. The original design scheme of "Eniac" computer was put forward by 36-year-old American engineer Mochri 1943. The main task of the computer is to analyze the trajectory of the projectile. The United States Ordnance Department allocated funds to support research and development, and set up a special research team, which was headed by Mochiri. The chief engineer is eckert, who is only 24 years old. Team member Gerstein is a mathematician and a logician Boxer. "Eniac”* * * * uses 18000 electron tubes, plus 1500 relays and other devices. It has a total volume of about 90 cubic meters, weighs 30 tons, covers an area of 170 square meters, and needs a large room more than 30 meters long to store it. It is a real monster.

This computer, which consumes 140 kwh per hour, has an operation speed of 5000 additions or 400 multiplications per second, which is 1000 times faster than the mechanical relay computer. When "Eniac" was publicly displayed, the trajectory of a shell was calculated in 20 seconds, which was faster than the flying speed of the shell itself. Eniac's memory is an electronic device, not a rotating "drum". It can complete tens of millions of multiplication operations a day, which is equivalent to a person working with a desktop computer for 40 years. It runs in decimal instead of binary. However, there are also a few electron tubes that work in binary mode, so the machine has to convert decimal into binary in its work, and then back to decimal when data is input and output.

"Eniac" was originally a special computer designed for ballistic calculation. But later, by changing the wiring mode inserted into the control panel to solve various problems, it became a universal machine. Its improved version was used in the development of hydrogen bombs. The "Eniac" program uses external plug-ins, and every time a new calculation is made in the software center, the line must be reconnected. Sometimes a few minutes or tens of minutes of calculation takes several hours or 1- 2 days, which is a fatal weakness. Another disadvantage is that the storage capacity is too small.

1996 February 15, on the occasion of the 50th anniversary of the advent of "Eniac", US Vice President Al Gore once again pressed the start button of this huge electronic computer that had been sleeping for 40 years at the grand commemorative ceremony held at the University of Pennsylvania. Gore said to the scientists who participated in the development of "Eniac" and are still alive: "I want to congratulate the pioneers who developed this computer that year." The two rows of lights on Eniac flashed to 46 with the exact number of knots, indicating that it appeared in 1946, and then flashed to 96, marking the beginning of the computer age for 50 years. [4]
