Schickard computer speakers
A computer is an electronic machine that accepts data, stores and processes data into information. The computer is able to work because there are instructions in its memory directing it. The abacus was an early aid for mathematical computations. Its only value is that it aids the memory of the human performing the calculation.

The history of the development of the computer is closely related to attempts to facilitate and automate large volumes of computation. Even simple arithmetic operations with large numbers are difficult for the human brain.
Man at all times of his existence needed tools for counting. In primitive times, a person had his own hand as such an instrument. At first, these were wooden sticks with notches, ropes with knots. The first mentions of this date back to BC, the parchment that already existed at that time was very expensive, and paper was not yet available. The urgent need for a better recording and counting tool has led to the emergence of abacus this tool is similar to Russian abacus.
According to the testimonies that have come down to us: the Egyptians used it already in the 5th century. In the seventeenth century.
Slide rules were used by generations of engineers and other professionals, right up to the advent of pocket calculators. The engineers of the Apollo program sent a man to the moon by performing all calculations on slide rule, many of which required an accuracy of digits. V Wilhelm Schickard invented the first mechanical calculator that could perform four arithmetic operations. Two centuries later in the Frenchman Charles de Colmar created an adding machine capable of multiplying and dividing.
They could memorize numbers, perform elementary arithmetic operations, and were operated by a human hand. Around , Charles Xavier Thomas created the first successful commercially available mechanical calculator, the Thomas Adder, which could add, subtract, multiply, and divide. Basically, it was based on the work of Leibniz. Mechanical calculators that count decimal numbers were used until the s. However, until the s, many subsequent developments including the machines of Charles Babbage and even the ENIAC were based on the more complex decimal system.
A special role in the development of computer technology was played by the work of the outstanding English scientist-mathematician Charles Babbage V early XIX v.
And he created such a machine. But Babbage dreamed of a universal machine that could solve arbitrary computational problems. Babbage devoted his whole life to the development of such a machine, which he himself called "Analytical".
He drew up a detailed diagram of the machine, completed a huge number of drawings of individual units, embodied some of its parts in metal, developed a project for performing scientific and technical calculations, where he predicted the main devices of a modern computer, as well as its tasks. The control of such a machine had to be carried out programmatically. For input and output of data, Babbage suggested using punched cards - sheets of thick paper with information applied using holes.
Babbage's ideas were far ahead of their time, they began to be really implemented at the end of the 19th century. Ada Lovelace, daughter of Lord Byron, translated and added commentary on the scholar's work Sketch of the Analytical Engine Her name is often associated with Babbage's name.
She is also claimed to be the first programmer, although this claim and the significance of her contributions are disputed by many.
Further development of science and technology made it possible to build the first computers in the s. It was a monster weighing about 35 tons. The Mark 1 used mechanical elements to represent numbers and electromechanical elements to control the operation of the machine.
Developers: John Mauchly and J. Presper Eckert. In the Soviet Union, the first electronic digital computer was developed in under the leadership of Academician S.
It was called "MESM" small electronic calculating machine. The founders computer science are rightfully considered: Claude Shannon - the creator of information theory. In , Claude Shannon showed that there is a one-to-one correspondence between the concepts of Boolean logic and some electronic circuits, which are called "Logic gates" , which are now commonly used in digital computers While at MIT, in his main work, he demonstrated that electronic couplings and switches can represent expressions of Boolean algebra.
So with my work A Symbolic Analysis of Relay and Switching Circuits he created the basis for the practical design of digital circuits,. Alan Turing - mathematician who developed the theory of programs and algorithms, John von Neumann - the author of the design of computing devices, which still underlies most computers. In the same years, another new science related to computer science - cybernetics: the science of management. The founder of cybernetics is an American mathematician Norbert Wiener At one time, the word "cybernetics" was used to refer to all computer science in general, and especially those areas that were considered the most promising in the 60s: artificial intelligence and robotics.
This is why robots are often referred to as "cybers" in science fiction books. And in the 90s, this word came up again to denote new concepts related to global computer networks - such neologisms as "cyberspace", "cyber shops" and even "cybersex" appeared. The American ENIAC, often referred to as the first general-purpose electronic computer, has publicly proven the applicability of electronics to large-scale computing. This has become a key moment in the development of computing machines, primarily because of the tremendous gains in computing speed, but also because of the emerging possibilities for miniaturization.
The created machine was times faster than all other machines of the time. After reworking the ideas of Eckert and Mauchly, as well as assessing the limitations of ENIAC, John von Neumann wrote the widely cited report describing the design of the computer EDVAC , in which both program and data are stored in a single universal memory. The principles behind this machine became known as the von Neumann architecture and served as the basis for the development of the first truly flexible, versatile digital computers.
The development of computers is divided into several periods. Computer generations of each period differ from each other in the element base and software. The first generation - electronic computers This is the era of the formation of computing. Most of the machines of the first generation were experimental devices and were built with the aim of testing certain theoretical positions.
The weight and size of these machines often required separate buildings for themselves. Entering numbers into the first machines was carried out using punched cards, and software control of the sequence of operations was carried out, for example, in ENIAC, as in calculating and analytical machines, using plugs and typesetting fields.
These machines occupied a large area, used a lot of electricity and consisted of a very large number of vacuum tubes. The next major step in the history of computer technology was the invention transistor. Transistors have become a replacement for fragile and energy-intensive lamps. Transistor computers are commonly referred to as the "second generation" that dominated in the second half of the 50s and early 60s The use of semiconductors in electronic computer circuits has led to an increase in productivity up to 30 thousand operations per second, and RAM up to 32 KB.
However, second generation computers were still quite expensive and therefore only used by universities, governments, large corporations. The second difference between these machines is that it appeared possibility of programming in algorithmic languages. On the second generation of computers for the first time there was what is called the operating system today.
Accordingly, the scope of application of computers expanded. Now it was not only scientists who could count on access to computing; computers have found use in planning and management, and some large firms have even computerized their accounts.
The third generation of computers. The explosive growth in the use of computers began with the so-called. This began with the invention of integrated circuits, which were independently invented by Nobel laureate Jack Kilby and Robert Noyce. This later led to the invention of the microprocessor by Ted Hoff Intel.
The development in these years of integrated circuits - entire devices and nodes of tens and hundreds of transistors, made on a single semiconductor crystal what is now called microcircuits and led to the creation of a computer of the 3rd generation.
At the same time, appears semiconductor memory, which is still used in personal computers as an operational one. The use of integrated circuits has greatly increased the capabilities of computers. Now CPU got the opportunity to work in parallel and control numerous peripheral devices. The computers could simultaneously process several programs the principle multiprogramming As a result of the implementation of the principle of multiprogramming, it became possible to work time-sharing online Users remote from the computer got the opportunity, independently of each other, to quickly interact with the machine.
During these years, the production of computers takes on an industrial scale. The firm IBM, which made its way into the leaders, was the first to implement a family of computers - a series of computers that are fully compatible with each other, from the smallest, the size of a small cabinet they did not make it smaller then , to the most powerful and expensive models.
Starting with the computer of the 3rd generation, the development of serial computers has become a tradition. Although the machines of the same series differed greatly from each other in terms of capabilities and performance, they were information, software and hardware compatible. The performance of these machines reached from thousand to 2 million operations per second, the amount of RAM reached from 8 MB to MB. For the computer series, the software was greatly expanded OS , high-level programming languages, application programs, etc.
The low quality of electronic components was the weak point of the Soviet third-generation computers. Hence the constant lag behind Western developments in speed, weight and dimensions, but, as the SM developers insist, not functionality In order to compensate for this lag, special processors were developed that allow building high-performance systems for private tasks. Back in the early 60s, the first minicomputers appeared - small, low-power computers that were affordable for small firms or laboratories.
Minicomputers represented the first step towards personal computers, prototypes of which were not released until the mids. Meanwhile, the number of elements and connections between them, which fit in one microcircuit, was constantly growing, and in the 70s, integrated circuits already contained thousands of transistors. This made it possible to combine most of the computer's components in a single small detail - which it did in by Intel by releasing the first microprocessor, which was intended for the newly appeared desktop calculators.
This invention was destined to make a real revolution in the next decade - after all, the microprocessor is the heart and soul of the modern personal computer. In addition, the border of the 60s and 70s is considered a fateful time. In was born the first global computer network - the germ of what we now call the Internet.
And in the same , the Unix operating system and the C programming language "C" appeared at the same time, which had a huge impact on the software world and still retain their leading position.
Unfortunately, since the mids, the harmonious picture of generational change has been disrupted.

The History and Future of Computers – Part 1
About years ago, a guy named Wilhelm Schickard made the world's first computer. It was a bulky machine that looked like an oversized typewriter, and it could add and subtract six-digit numbers. It was difficult to operate, was ridiculously expensive, and had no USB ports. But it was the beginning of a revolution. Today's computers are not very different - only they do billions of such calculations every minute. And they're much smaller - and prettier. It took another years to make a computer that was of actually any use to us nonintelligentsia. I was born in the year , so I have experienced a completely computer-aided life.

An electronic calculator is typically a portable electronic device used to perform calculations , ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early s. Pocket-sized devices became available in the s, especially after the Intel , the first microprocessor , was developed by Intel for the Japanese calculator company Busicom. They later became used commonly within the petroleum industry oil and gas. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers.
What, people managed before computers?
It all started back in with a few technology enthusiasts and has steadily grown since. The topics presented at GPN are widely varied. The bulk of talks and workshops focus on hard- and software development, as well as digital rights and privacy on the internet. Beside those obvious topics we have had many talks answering questions like "How do I fly a spaceship? The GPN is organized by the Entropia e. The ZKM is a museum focused on digital art. During the event visitors can freely move through the GPN as we don't limit access. Because of that we ask possible speakers to try to speak to a general audience and not only to the digital-natives found at more specialized events.
The definition of Schickard in the dictionary is a large crater in the SW quadrant of the moon, about kilometres in diameter.

This is it, the first stop. The beginning of computing. Why did people begin building calculation machines in the first place, you might ask? Well, mostly they were just a bit lazy really. The little beads are counters, which you can use to make calculations using Roman numerals. Moving on, here we have a reconstructed tally counter from the middle ages.
A computer is a device that can store and return the information we process whenever we want. Today's computers are capable of tracking generalized sets of processes called programs. These programs enable computers to perform a wide variety of tasks. A complete computer containing the hardware, operating system main software and peripheral equipment required and used for "full" operation can be referred to as a computer system. This term can also be used for a group of computers connected and working together, particularly a computer network or cluster of computers.
