Who Invented Computer And When? | Origin And Use Of Computer | Who is the true father of computer?
Who Invented Computer And When? – Computers are one of the most amazing achievements of modern science. It plays an important role in modern life. An electronic calculator that can count, write, and solve very complex problems. Computers have created roads in every human activity. Friends of students, businessmen, entrepreneurs, scientists, etc.
The word computer comes from the word compute, which means to calculate. Computers are installed in offices, business houses, laboratories, and spacecraft. No need to wait in long lines today. Tickets are issued by computer. Computers have made life easier and more complete.
A Neolithic structure at Stonehenge near Salisbury in England is believed to be the oldest computer. It is believed to have been built about 4000 years ago. It consists of a stone circular structure believed to have been dedicated to the sun god. It was used to predict celestial events, such as the orbits of various planets. John Napier (1552 – 1617) developed logarithms to facilitate multiplication and division.
The slide rule was an extension of the logarithm. In fact, a scientist named Charles Babbage invented the modern computer in his 19th century. Early computers used vacuum tubes. A few years later, Dr. Howard Alken of Harvard University designed the first mechanical computer, the Automatic Sequence Control Computer.
The computer has his two models, analog and digital. The first is a measurement, the second is a calculator. Digital computers are more common today. Numbers in Latin mean fingers. We used to count on our fingers. Computers are used to perform highly sophisticated tasks. These are used to control the direction of rockets and missiles. Such computers were used in World War II. A lot of research has been done to improve the existing ones.
A computer program is a set of coded instructions for a computer to follow. Writing these programs is called computer programming. Computers, with their sophisticated capabilities and extraordinary ability to perform tasks, cannot replace humans. It can’t think for itself. Only programmed tasks can be executed. The computer can control the movement pattern of the electrons, producing the desired image on the screen, such as the image on a television screen produced by the impact of the electrons.
Today, computers can be used to create accurate scale maps in a short amount of time. We can provide photos, maps, etc. Computers are also used in satellites to predict the weather. Hospital computers can keep doctors informed of a patient’s condition. In fact, computers will do most of our work in the 21st century.
Who Invented Computer And When? | How Big Was The First Computer
Who Actually Invented The Computer | Who was the first computer in the world?
Many people disagree about when the first computer was built. In fact, the first true conception of the idea of a computer was J.H. Smith in 1782. Although he never built a computer. His concept was called a diff engine.
The differential engine was put on the back burner until his 1822 when Charles Babbage picked up the concept. He used his decimal number system and created a machine operated by cranking a handle. Babbage was funded by the British government for research, but he later cut off that support.
This didn’t stop Babbage, though he designed another Analytical Machine, which he later improved upon and installed Differential Engine #2. All this was done between his 1834 and his 1869 years. Babbage took a leap with his designs.
Still others claim that Babbage’s machine was the first electronic computer. An earlier concept was called the Antikythera His Machine, a mechanical device used to calculate the position of the constellations.
This “oldest computer” was found in a Mediterranean shipwreck and dates back to 250 BC. It is unknown who designed this early device, but it is speculated that it was designed by Archimedes, given its similarity to some of Archimedes’ other mechanical devices.
However, some argue that the abacus was actually the first computer. They were invented in China between 2600 BC and 300 BC. These abacuses were used by Chinese clerks and merchants and are considered by many to be the first computers.
Originally from Cambridge, England, Alan Turing was sent to a secret base in Bletchley Park, where a World War II puzzle code used by the Germans was being developed. Until recently, the name of this computer was his Colossus, kept secret. It was shattered into pieces at the end of the war.
The first known “modern computer” was invented by a German engineer named Konrad Zuse in 1941 during World War II. This computer he named Z3. It was an analog computer designed to stimulate the rocket’s guidance system.
Some research shows that Babbage didn’t create the entire machine. So it was Zuse who invented the first electronic computer.
So it’s not easy to answer exactly who invented the computer. Precisely, we must say who contributed to the creation of the computer. So many people throughout history, both unsuccessful and successful, have helped these inventions.
So the first electronic computer was invented by John Vincent Ensoff. It was named ABC, which stands for Anatasoff Berry Computer.
Many may think that IBM designed his PC first, but in reality he had the MITS Altair 8800, Apple II, TRS80, Atari 800 and of course the Commodore 64 before that. . Some say Altair wasn’t the first, it was Berkeley Enterprises’ Simon.
As you can see, who invented the first computer is truly elusive and will last forever. But let’s thank all these people who came up with the incredible machine. Our life is difficult without it.
Best Facts About Computer History | Who Invented The Modern Computer
Much of our life today depends on the existence of computers. Whether we use them to work, communicate with loved ones who are not nearby, watch movies or get information, we can no longer imagine living without computers. Its history is quite recent, starting with the famous abacus, later scientists were able to develop more sophisticated formulas that simplified the operation of these machines.
Therefore, besides the abacus, many mathematicians and scientists worked to improve the machine, which he initially had only one function: calculation. Among the first computers can be counted the “arithmometer” manufactured in 1820, the first mass-produced calculator to perform multiplication using the approach developed by Leibniz. It can also do segmentation with the help of the user. In 1832, Charles Babbage invented the “Analytical Engine”.
This is a programmable calculator that can perform addition in 3 seconds and multiplication or division in 2-4 minutes. Compared to today’s computers, the machines were very large and very slow.
With the outbreak of World War II, new weapons and military equipment were invented that needed to be controlled by computers. As a result, this need has led to electronic digital computers that calculate ballistic tables for these new weapons. The father of electronic numerical integrators and calculators was John Mauchly, who together with his colleagues created a computer that was 1000 times faster than his older generation computers.
He can also multiply two numbers at a rate of 300 per second by finding the value of each product from a multiplication table stored in memory. Although the machine was very large and consumed a lot of energy, it is considered the most efficient high-speed electronic digital computer of its generation. It was only used from 1946 until his 1955 as it was made obsolete by later inventions.
As better computers came along, the 1950s marked the rise and development of magnetic core memory, the ancestor of today’s commonplace RAM. However, in the 1960s, scientists realized that the smaller the components and computer circuits, the more efficient the machines, and continued their research into the 1980s. In the 1980s, very large-scale integration became commonplace in computer building blocks.
This new device required hundreds of thousands of transistors on a single chip. Also in the 80’s microprocessors came into use, making this decade one of his richest inventions in computer history. It was already in good shape and ready to receive new members.
The “shrink” trend is gone and ended with the introduction of the personal computer (PC), a small, inexpensive programmable machine for individuals to purchase and use. Today we use laptops and technology has not stopped evolving. That leaves me wondering how computers will evolve in the future. However, computers are seen as devices developed with the primary purpose of simplifying human work and the need for efficient machines at all times.
Today’s computers are products of the digital revolution. When we talk about computing, we are talking about the environment of 1s and 0s that links all the programs, graphics, and communications we use. Often teased, it’s just another emptiness, but that little concept means a lot.
In the early days of computing, there was a race between analog and digital computing for a practical and convenient calculator. In fact, analog computers have existed since ancient times and were used to calculate the positions of stars and planets. Perhaps the best-known example of an analog computer is the slide rule. But just as analog slide rules were replaced by digital calculators, analog computers were replaced by digital competitors.
Analog computers are powerful because they have many states and are not constrained to just 1s and 0s. It can solve very complicated equations. However, the power has a complicated structure and mass production is not easy. The transistor and later solid state and integrated circuit technology made digital computers ubiquitous.
