History of the development of computing tools
#History of the development of computing tools ##1. Early computing tools 1. ** Fingers ** - The earliest calculation tool in human history could be said to be the finger. In the early civilizations, people used their fingers to do simple counting. However, as life and transactions became more complicated, fingers could no longer meet the needs of counting. 2. ** Knot the rope to record the events ** - Then, a method to record things with a rope appeared. People tied knots on long ropes to record or count, using different colors and lengths of ropes to represent different values or events. This was much more convenient than using stones and shells to count. In ancient China books, there was a record of " ancient knots to rule." 3. ** Counting ** - Later, people invented counting rods, which were small sticks made of bamboo, wood, iron, jade, and other materials. The counting rod used the decimal system. By placing and moving the small rod to calculate, it could represent many digits and do multiplication calculations. When expressing a large number of digits, the vertical type is used for one digit, the horizontal type is used for ten digits, the vertical type is used for one hundred digits, the horizontal type is used for one thousand digits, and so on. When it meets zero, it is empty. ##2. Traditional computing tools 1. ** Abacus ** - The abacus evolved from counting rods and was invented in China Eastern Zhou Dynasty, about 2600 years ago. It was recognized as one of the earliest calculation devices. It was light and easy to carry, and could perform basic arithmetic operations. The common seven-bead abacus had two beads on the top and five beads on the bottom. It was easy and fast to calculate on the abacus. It was widely used before the appearance of Arabic numbers. 2. ** Slide-rule ** - In 1520 AD, the Englishman Gant invented the slide rule. It was composed of three parts: the upper and lower ruler, the sliding ruler, and the vernier. It was mainly used for some special calculations, which was fast and time-saving. However, the accuracy of different slide rulers might be different, and it was mainly used for rough calculations. ##3. Computational Tools in the Industrial Era 1. ** Mechanical difference engine ** - In 1822, a model of a mechanical difference engine appeared, which could increase the speed of multiplication and improve the accuracy of digital tables. However, it had many parts and weighed in tons. 2. ** Electromechanical calculator ** - In 1944, scientist Aiken of the MIT developed an electro-mechanical computer. It was a combination of mechanical and electronic calculation, with the advantages of high calculation accuracy and good reliability. It was composed of mechanical switches, gears, gliders, counters, arithmetic units, input and output equipment, as well as some electrical and electronic components. However, it was large, heavy, inconvenient to carry, and the cost of equipment was relatively high. ##4. Modern computing tools 1. ** Electronic calculator ** - In the 18th century, the German mathematician Leibniz designed and manufactured calculators that could perform addition, deduction, multiplication, division, and root operations based on Pascal's invention, which promoted the advancement of computing tools. Since then, computer technology had developed along two paths. One was the development path of various desktop machines and large-scale mechanical computers, and the other was the development path of using relay as a computer circuit component. With the development of computer technology, the computing power was constantly increasing from the transistor-based computer to the integrated circuit computer to the VLSI-based computer. Nowadays, with the development of artificial intelligence, big data, and other technologies, the application of computing tools became more and more widespread, reaching into all aspects of life.

Evolution of computing tools
The evolution of the calculation tool was as follows: 1. The earliest calculation tool might have been the " finger ", but as the complexity of life and transactions increased, fingers could not meet the needs of counting. Thus, the " knotted rope record " appeared. People represented different values or events through ropes of different colors and lengths. 2. Later, he invented counting rods. They were small rods made of bamboo, wood, iron, jade, and so on. They used the decimal system. By placing and moving the small rods to calculate, they could represent multi-digit numbers and do multiplication calculations. When multi-digit numbers were represented, they were used vertically, horizontally, vertically, horizontally, and so on. When they encountered zeros, they were empty. 3. The counting rod evolved into the abacus, which was light and easy to carry, and could perform basic arithmetic operations. A common abacus was a seven-bead abacus with two beads on the top and five beads on the bottom. It was easy and fast to calculate on the abacus and was widely used in China. 4. In 1520 AD, the Englishman Gant invented the slide rule, which was composed of three parts: the upper and lower fixed ruler, the sliding ruler, and the vernier. It was mainly used for rough calculations in special operations. 5. In 1822, the mechanical difference engine appeared. It had many parts and was heavy. It could increase the speed of multiplication and improve the accuracy of digital tables. 6. In 1944, scientist Aiken of the MIT developed an electro-mechanical calculator. It used a combination of mechanical and electronic methods to calculate. It had the advantages of high calculation accuracy and good reliability, but it was large, heavy, inconvenient to carry, and the equipment cost was high. 7. In modern times, the German mathematician Leibniz in the 18th century designed and manufactured calculators that could perform addition, deduction, multiplication, division, and square root operations based on Pascal's invention. After that, computer technology developed along the two development paths of desktop machinery and large-scale mechanical computers, and the use of relay as computer circuit components. From the development of the crystalline computer to the integrated circuit computer, and then to the ultra-large-scale integrated circuit computer, the computing power continued to improve. Now, with the development of artificial intelligence, big data, and other technologies, the application of computing tools became more and more widespread.

The History of Human Writing Tools
The development of writing tools had gone through a long process. At first, archaeologists believed that the earliest writing tools were sharp stones and branches. People used paint made from crushed minerals, berries, crustaceans, or plants to paint on cave walls and dried animal skins. In ancient Egypt, ancient Greece, and ancient Rome, swamp reeds became the earliest pens used by people. At the same time, sharp ivory, bones, or metal rods were also used to draw symbols or patterns on wax plates. The outer feathers of large birds were also used as pens. In the late Shang Dynasty, carvings on tortoise shells and animal bones were popular. The most famous one was the oracle bone inscriptions unearthed in Xiaotun Village, Anyang. The Babylonians sharpened the reeds and wrote cuneiform on the clay board. The ancient Egyptians began to use papyrus around 3000 B.C. The raw material was the stem of papyrus, which could last for thousands of years in a dry environment. In addition, in ancient times, animal skins, cattle's shoulder blades, bamboo, wood, bark, etc. could be used as carriers for writing. For example, there were bamboo slips in China. Later, around 1809, fountain pens began to be used for writing, followed by the modern ballpoint pen. With the development of technology, we now use plant materials (such as wood pulp) to make paper. After the Gutenberg printing press (lead type printing press) was invented in 1450, books could be printed in large quantities. Nowadays, in addition to traditional writing tools and paper, we can also use e-readers (such as iPad, mobile phones) to read books. Writing tools and writing media are more diverse.

computing equipment
Calculating tools referred to the tools used in calculations or objects that assisted in calculations. Since the birth of mathematics, people had been constantly looking for convenient and accelerated computing tools. There were many calculation tools in ancient China. For example, the "calculation table" of the Warring States Period was composed of bamboo slips. It was filled with numbers in the form of a table. It could perform two-digit multiplication and division, multiplication with scores, square root, and other operations. When using it, the numbers were split, and the corresponding numbers were found on the calculation table. The result was calculated in a specific way. The appearance of the "calculation table" was related to the fine management of the country at that time and the frequent trading. It not only solved the calculation needs, but also gave birth to the concept of negative numbers. The Ming Dynasty mathematician Wang Wensu's book "The Treasure of Mathematics" had the concept of "derivative", which was the cornerstone of calculus. In addition, from the table to the counting rod to the abacus, the abacus was an ancient and unique calculation tool. The earliest form appeared in the Han Dynasty and was gradually finalized in the Song Dynasty. Its standard style was a rectangular wooden frame with multiple parallel beads. Usually, there were 13 gears with a total of 91 beads. There were seven beads on each rod. Two beads on the top row represented five, and five beads on the bottom row represented one. By pushing and pulling the beads, the calculation was done. Unlike modern calculators, it relied on the coordination of the brain and fingers. It was a mathematical skill exercise and thinking art. In 2013, it was included in the list of intangible cultural heritage by the United Nations. In modern times, there were also various calculation tools, such as the plumber's special-shaped calculation tool, which could calculate different lengths such as L1 and L2, as well as all types of calculations for the middle section and the elbow (input the ground to the elbow's horizontal port H); the box system had an automatic mortgage calculation function, and the result could be obtained instantly by entering the mortgage information (loan type, repayment method, monthly payment amount, etc.); there were also key, pin, and interference connection geometry and strength verification calculation tools. It was free to install, and could calculate the strength of flat keys, tangential keys, and many other types of keys.

History of Computer Development
The history of computer technology can be traced back to the early 20th century. Vacuum tube computers: In the early 1940s, people began to use vacuum tubes to make computers. These computers were slow, required a lot of power, and were easily damaged. In the mid-1950s, people began to use the crystal to make computers. These computers were faster, more reliable, and did not require a lot of electricity. Integrated Circuit Computer: In the late 1960s, people began to use integrated circuits to make computers. These computers became more compact, faster, and easier to maintain. Personal computers: In the late 1970s, people began to manufacture personal computers. The emergence of these computers made it easier for people to process data and communicate. Internet: In the early 1990s, people began to use the Internet to transmit data. With the continuous development of the Internet, people can use the Internet to carry out a wider range of communication, learning, entertainment and other activities. As time passed, computer technology continued to develop and had a profound impact.
The History of the Development of Fictions
A novel is a genre of literature that usually uses fictional stories as the theme to convey the author's thoughts and emotions by describing the characters, plot, and environment. The development of novels can be traced back to ancient times, but some important characters and plots have already appeared in ancient novels. In the Middle Ages, novels became an important literary form, such as the Old and New testaments of the Bible. These novels usually contained a large number of myths, legends, and historical events, which became an important medium for people's beliefs and cultural exchanges. In the 19th century, the novel began to receive attention and became an independent literary form. Many famous novelists emerged during this period, such as Charles Dickens, Jane Austen, Victoria Beckham, and others. Their works were not only popular at the time, but they are also loved and read by people now. At the beginning of the 20th century, novels began to develop in a more complex and diverse direction. During this period, many new literary schools emerged, such as realism, post-realism, feminism, etc. These schools not only challenged the traditional literary forms but also led the development of modern literature. In the middle of the 20th century, novels became one of the main forms of world literature. Many famous novelists emerged during this period, such as Hugo, Dickens, Maupassant, Tolstoy, etc. Their works were not only popular at the time, but they are also loved and read by people now. Nowadays, novels had become one of the most popular forms of literature. There were many excellent novelists and their works in both modern and contemporary literature.
History of newspaper development
The history of newspapers can be traced back to the end of the 19th century, when the first newspaper was produced by the German doctor Karl Max and his assistants. In the early 20th century, newspapers became an important media, reporting on many major events such as the First World War, the Russian Revolution, and the rise of Nazism. With the development of technology, the types of newspapers became more and more diverse. In the 1930s, the first electronic newspaper appeared in the United States, which displayed news content on a computer screen. In the 21st century, the popularity of the Internet and smart phones has made the development of newspapers face new challenges, but newspapers still continue to play an important role in the media. Nowadays, many people get news through newspapers or social media.
The History of Computer Development
The development of computers could be divided into several stages. Before 1946, there were relay computers, such as the Harvard Mark I, which was an mechatronics computer and the prototype of modern computers. 1946 - 1957 was the first generation of electron tube computers, represented by ENIAC. It used electron tubes, which were large in size, high in power consumption, and slow in speed. It was mainly used for scientific calculations. From 1958 to 1964, it was a transistor-based computer. The transistor-based computer replaced the vacuum tube and improved its performance. From 1964 to 1970, integrated circuit computers were introduced, and the size of computers was further reduced. After 1970, there were large-scale integrated circuit computers with higher performance. Now, it was still developing towards the fifth generation of artificial intelligence computers.
