• Who developed the first computer in the world. The first computers - the beginning of the era of high technology. How the computer got its name

    Acquaintance with the computer took place not so long ago, but its appearance was preceded by a long history of creation.

    A bit of history

    Blaise Pascal and Wilhelm Leibniz' adding machine are considered the ancestors of the modern personal computer. The term "computer" was first mentioned in the 18th century. Then this term was applied to any mechanical computing device that could perform the simplest operations - addition and subtraction.

    In the Oxford Dictionary, the word "computer" was interpreted as "computer".

    Later, at the beginning of the 19th century, a more “intelligent” machine was invented that could solve even simple equations. Even later, they were able to create the first analytical multifunctional machine that works with punched cards. Given the close attention of scientists to these devices, their modernization took place at an accelerated pace. In a short time they were equipped with electrical relays and vacuum tubes.

    A long way from the first computer to the modern computer

    In 1946, the first computer was presented to the world. True, that machine was many times larger than a modern computer and absorbed a fairly large amount of electricity. The weight of the first computer was approximately 30 tons. Only large, wealthy companies and enterprises allowed themselves to use such computers.

    In the early 60s, thanks to the invention of transistors, manufacturers were able to release the first mini-computer PDP-8. The computer was equipped with RAM for storing information, information was learned to be stored on magnetic disks. The leading position in the production of computers at that time was taken by IBM, which to this day remains the largest computer manufacturer in the world.

    A significant event in the development of personal computers is the creation by Bill Gates of the Altair Basic language interpreter, which made it possible to create various programs for computers.

    Since the creation of Altair, the production of computers began to be massive. Many manufacturers of PCs and software for them began to appear.

    From that moment on, the main emphasis was placed on improving the quality and versatility of this technology, which allowed a person to use a multifunctional and compact "super device" - a modern computer.

    The history of the invention of computers

    1 How it all began

    At the end of the 19th century, Herman Hollerith in America invented perforating machines. They used punched cards to store numerical information.

    Each such machine could execute only one specific program, manipulating with punched cards and numbers punched on them.

    Counting and perforating machines perforated, sorted, summed up, printed numerical tables. On these machines it was possible to solve many typical tasks of statistical processing, accounting and others.

    G. Hollerith founded a company producing punching machines, which was then transformed into IBM, now the world's most famous computer manufacturer.

    Relay computers were the immediate predecessors of computers.

    By the 30s of the 20th century, relay automation was greatly developed, which made it possible to encode information in binary form.

    During the operation of a relay machine, thousands of relays switch from one state to another.

    Radio technology developed rapidly in the first half of the 20th century. The main element of radio receivers and radio transmitters at that time were vacuum tubes.

    Electronic lamps became the technical basis for the first electronic computers (computers).

    2 First computer

    The first computer - a universal machine on vacuum tubes - was built in the USA in 1945.

    This machine was called ENIAC (stands for Electronic Digital Integrator and Computer). The designers of ENIAC were J. Mouchli and J. Eckert.

    The counting speed of this machine exceeded the speed of relay machines of that time by a thousand times.

    The first electronic computer ENIAC was programmed using the plug-and-switch method, that is, the program was built by connecting the individual blocks of the machine on a switching board with conductors.

    This complex and tedious procedure for preparing the machine for work made it inconvenient to operate.

    The main ideas, according to which computing technology has been developing for many years, were developed by the largest American mathematician John von Neumann.

    In 1946, the journal "Nature" published an article by J. von Neumann, G. Goldstein and A. Burks "Preliminary consideration of the logical design of an electronic computing device."

    This article outlined the principles of the design and operation of computers. Chief among them is the principle of the stored program in memory, according to which the data and the program are placed in the general memory of the machine.

    The fundamental description of the device and operation of a computer is commonly called the architecture of a computer. The ideas outlined in the article mentioned above were called "computer architecture by J. von Neumann."

    In 1949, the first computer with the Neumann architecture was built - the English machine EDSAC.

    A year later, the American computer EDVAC appeared. The named machines existed in single copies. Serial production of computers began in the developed countries of the world in the 50s.

    In our country, the first computer was created in 1951. It was called MESM - a small electronic calculating machine. The MESM designer was Sergey Alekseevich Lebedev.

    Under the leadership of S.A. Lebedev in the 50s, serial tube computers BESM-1 (large electronic calculating machine), BESM-2, M-20 were built.

    At that time, these machines were among the best in the world.

    In the 60s, S.A. Lebedev led the development of semiconductor computers BESM-ZM, BESM-4, M-220, M-222.

    The outstanding achievement of that period was the BESM-6 machine. This is the first domestic and one of the first computers in the world with a speed of 1 million operations per second. Subsequent ideas and developments by S.A. Lebedev contributed to the creation of more advanced machines of the next generations.

    Our time of computerization obliges every educated person to know a lot of things directly related to computer technology. And you can start by studying when the first computer appeared. Agree, few people think about the origin of the computer.

    The history of the creation of the first computer

    The computer as we see it now was not always like this. The "life path" of the computer can be easily traced. It began with the invention by Blaise Pascal in 1642 of a device capable of adding and subtracting decimal numbers - the Pascaline. It was difficult to call the first computer in the world a computer, because it was something more like a calculator. This computer performed only two operations - addition and subtraction. Then, in 1653, multiplication and division were added to these functions. Further, the development of the functionality froze somewhat, they began to focus on the appearance, that is, they tried to clothe all the same options in a more compact and less cumbersome shell. It wasn't until 1822 that a machine was invented that could solve simple equations. It was a turning point in the history of computer technology. After that, automated computing devices evolved at a tremendous speed. Already in 1946, a new computer appeared to the world. Of course, comparing the first computer and a modern PC, one can smile skeptically, because it is not clear how a machine weighing 30 tons could turn into something that even a woman can easily lift.

    Who is the developer of the first computer

    Of course, the one who invented the first computer in the world, did a great job in the development of technology. So who is this person who introduced the first computer to the world? It was a scientist of German origin Konrad Zuse. The very first computer in the world, according to Wikipedia, is precisely the computer invented in the forties of the 20th century, since it contained all the basic functions of a modern computer. But the size of this technique was still incredibly large, sometimes taking up an entire room alone. And only with the invention of the microprocessor, for which thanks to Tedd Hoff, the computer began to approach in size to the PC familiar to us.

    By the way, the PC gained wide popularity after the start of competition between two companies - Apple and Microsoft. In the battle for customers, these companies improved and improved their products, delighting us with compactness and functionality. Since the first PC was invented, relatively little time has passed, but the differences between that device and the current one are huge. We can only guess what improvements await the computer in the future.

    Computers, without which our life is not possible, in fact, appeared not so long ago. Representatives of the older generation not only did not use computers during their studies at schools and institutes, but, as a rule, had no idea what it was. The era of computers and even electronic computers - computers - as we called the first computers came into our lives relatively recently. Although their most distant predecessor - the abacus (abacus), appeared in ancient Babylon 3000 BC.

    The first person to invent the first digital computer was Blaise Pascal. In 1642, he presents the Pascalina, the first mechanical digital computing device that was actually implemented and gained fame. The prototype device added and subtracted five-digit decimal numbers. Pascal made more than ten such calculators, with the latest models operating on numbers with eight decimal places. This discovery started it all...

    Since that time, many mechanical devices have been invented that allow for not very complex calculations. The main progress was observed from the end of the 19th century, and the peak occurred in the first half of the 20th century. And so, in 1938, the more complex first mechanical programmable machine Z1 was created by the German engineer Konrad Zuse. On its basis, in 1941, he also created the first Z3 computer, which has all the properties of a modern computer.

    Who invented the first electronic computer and when? After all, it is he who is the real prototype of modern computers. And it happened quite soon after the invention of Konrad Zuse. In 1942, American physicist John Atanasoff and his graduate student Clifford Berry designed and began to assemble the first electronic computer. The work was not completed, but had a great influence on the creator of the first electronic computer ENIAC. The person who invented the ENIAC computer, the first digital electronic computer, was John Mauchly, an American physicist and engineer. John Mauchly summarized the basic principles of building a computer based on the experience of developing machines and in 1946 the real electronic computer ENIAC appeared to the world. The head of the development was John von Neumann, and the principles and structure of computers he outlined later became known as von Neumann.

    So the questions about what year the computer was created, where the first computer was created and who created the first computer can be answered in different ways. If we are talking about the first computer in general (in this case, a mechanical one), then Konrad Zuse can be considered the creator of it, and Germany can be considered the country in which the first computer was invented. If we consider the electronic computer to be the first computer, then it will be ENIAC, the inventor, respectively, John Mauchly, and the country - the United States.

    The first computers were still far from those that we now use - personal computers. They were huge, occupied significant areas, commensurate with the area of ​​a multi-room apartment, and weighed several tens of tons! Personal computers (PCs) appeared much later.

    And who then created the first personal computer? The creation of the first personal computers became possible only in the 1970s. Some people began to assemble computers at home for the sake of research interest, since there were practically no useful applications for computers at home. And in 1975, the first personal computer Altair 8800 appeared, which became the first commercially successful PC. The creator of the first personal computer was the American engineer Henry Edward Roberts, who was also the founder and president of Micro Instrumentation and Telemetry Systems, which launched the first PC. Altair 8800 was the "chief" of the population's computerization boom.

    The first personal computers, and even computers of the early 90s, were many orders of magnitude weaker than modern ones. Suffice it to say that the amount of memory of a modern, not the coolest "flash drive" is comparable to the entire disk memory of several thousand (!!!) personal computers of the early 90s. And so it is similar for all other indicators. A fantastic breakthrough in the performance of modern personal computers in the 2000s is associated primarily with the development of new technologies in the field of electronics and nanotechnology.
