As Charles Babbage once said "With every increase in knowledge, as well as with the invention of every new tool, human labor is reduced." Since Charles said that new things are achieved through new knowledge or thoughts, I will have to talk about people who were influenced or encouraged by Charles Babbage's knowledge to develop computers. Mathematics is the foundation of a computer because everything we calculate can be done with a computer. According to Dinesh, “the word “computer” comes from the Latin word “computare” which meant a person who did calculations. The essay will take place in many places based on the different countries of the inventors and will touch a bit on World War II. According to Ian (2015), “as we have experimented with basic virtual reality headsets that have been programmed using a computer, we can see that there is a lot to invent as we now have the new Huawei which uses three cameras. We don't know what the future holds because many computers are developed every year.' Who knew that as time goes on we will have phones with three cameras? Or maybe we will have invisible phones? We'll see what the future holds for us! And we'll talk about it in the essay. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

Life before the invention of "computers" was hard, just like today if they stopped making computers or stopped all computers working, life would stop. The reason is that everything we use is programmed by a computer or is a computer. That's why I say that about 95% of our life depends on them. The development of computers has changed our lives completely and we cannot imagine our life without them. According to Mastermind Abacus (2013), "the first apparatus used to solve mathematical problems and other things was an abacus, invented in the early 500s BC in Asia and is still used by children for counting purposes." The invention of an abacus dates back many years in different countries, so we don't know the exact time of development/discovery. The first common computer was designed in 1834 by a British mathematician, Charles Babbage. It was designed to store memory and solve analytical problems, the machine was called the Analytical Engine. 'Charles designed three powered machines, one was the Difference Engine (first machine) in 1821, the Analytical Engine in 1834 and then the Difference Engine (second machine) in 1847. The machines were named according to their mathematical principle. The Difference Engine was designed to solve polynomials while the Analytical Engine solves arithmetic problems', Computer History Museum. Financing for the first machine was not granted because the machine had to use durable materials which would have cost a lot and the government did not want to waste money on something they were not sure would work. After the difference machine (second machine) was built in 1991, the machine worked as Charles had intended. From the Computer History Museum's research, "they found that before people started developing their own machines, even Charles Babbage, they were asked several questions by the government." The main one was to prove/prove that the mathematical statements were true or not'. After analyzing how computers should work, the development of computers began. Crash Course (2017), 'the Abacus, from 2700-2300 BC, was used for mathematical purposes and to count the country's population, as Sumerian society was inincrease. But before the society started to expand, the number of people was small due to the division of some places (cities/villages). So it was easy to use an abacus and they can add up the total number of people in each city/village that falls within a certain country.' They were used in many countries for these things. 'In England, they calculated/counted that the population every 10 years, was mainly used for tax purposes. Over the years the population has grown rapidly, due to the birth rate and visitation rate and it has become more difficult to calculate/count. It was then that Herman Hollerith, an American inventor, invented a tabulating machine that could store memory, because they faced the same thing as in England, and it was also used for some other thing such as dates of marriage, birth or death, using index cards perforated. The story of Alan Turing will not be forgotten for the role he played during the invention of the computer. 'Alan Turing was a British computer scientist and mathematician. He is often called the father of the modern computer,” said Daniele (2016), the reason being that the machine he built, compared to the one we use now, serves the same purpose. According to the Imperial War Museums, “Alan Turing built a machine that could decipher and create codes, which were used by the Germans to communicate. He built the machine to learn about Germany's plans with other countries that were on the same side during the war, in World War II. The machine that i Germans used to communicate yes called the "Enigma" and was invented by Arther Scherbius, said Andrew (n. d) after World War I. As soon as Turing discovered the Enigma he went to the US government to figure out how to put the machine together.' 'Meanwhile in Germany, a German computing pioneer, Konrad Zuse, built the first programmed electric car but during the time he finished building it, no one recognized his work, not even the newspapers, only his parents did tried to talk to the German Air Force about the device he was building, but they didn't see any use in it, since they were at war," Pottenger(n. d) said. He thought his machine would help as there were people doing calculations during the war, the purpose he built the machine was to make calculations easy for "computers", "computers" were people doing calculations. Even in the years after his invention, when people were rewarded for what they created, he achieved nothing. In 1939, Alan Turing's machine was built and he knew where their opponents were planning, they managed to save millions of lives. Another machine that played an important role and changed our lives is the Eniac machine which was built by John Mauchly and J. Presper Eckert. The machine is called the first general-purpose electronic machine used to solve numerical problems and was the fastest machine ever built. The machine was built at the University of Pennsylvania in 1944 and finished in 1946, with the help of engineering students. John was an American physicist and needed help with his car. That's when he asked Eckert for help because he was an electrical engineer. “In 1947 the Eniac was used in the army for artillery firing tables and for adjusting target accuracy,” Mary (2018). The Eniac took up a large amount of room space and had to use a large amount of electricity to operate, luckily they got funding from the US Army. There are many people who have played an important role in the inventions, some have been recognized and some not, some have obtained the patent and some not, but their work must be respected. 'After.
