Computer history

 









  • The first calculating machine: In 1642, the French mathematician Blaise Pascal invented a machine that could perform basic arithmetic calculations. This device, known as the Pascaline, was the first mechanical calculator.

  • The difference engine: In the early 19th century, the English inventor Charles Babbage designed a machine called the difference engine, which could perform complex mathematical calculations automatically.

  • The analytical engine: Babbage's next invention was the analytical engine, which was designed to perform more general-purpose calculations. Although the machine was never built during Babbage's lifetime, it is widely regarded as the forerunner to the modern computer.

  • The electromechanical computer: During World War II, engineers in the United States and Britain developed electromechanical computers that could perform complex calculations for military purposes. The most famous of these machines was the ENIAC (Electronic Numerical Integrator and Computer), which was completed in 1945.

  • The first electronic computer: The first electronic computer, the Electronic Delay Storage Automatic Calculator (EDSAC), was built at the University of Cambridge in England in 1949. It used vacuum tubes instead of electromechanical switches to perform calculations.

  • The first commercially available computer: In 1951, the UNIVAC (Universal Automatic Computer) became the first commercially available computer. It was used primarily for scientific and engineering applications.

  • The invention of the microprocessor: In 1971, the Intel Corporation introduced the first microprocessor, the Intel 4004. This breakthrough allowed computer designers to build much smaller and more powerful machines.

  • The personal computer revolution: In the late 1970s and early 1980s, a number of companies, including Apple and IBM, introduced personal computers that were affordable and easy to use. This sparked a revolution in computing that continues to this day.

  • The internet: In the 1990s, the World Wide Web and the internet revolutionized the way people communicate, access information, and conduct business. Today, the internet is an essential part of everyday life for billions of people around the world.

These are just a few of the key milestones in computer history. Over the past few decades, computers have continued to evolve and become increasingly powerful, and it's likely that they will play an even more central role in our lives in the years to come.

History of great wall china

  The  Great Wall of China  is an ancient wall in  China . The wall is made of cement, rocks, bricks, and dirt. It was finished in 1878 [1]  and it was meant to protect the north of the  empire  of China from enemy attacks. It is the longest structure humans have ever built. It is about 21,196 kilometers long, 9.1 metres (30 feet) wide and 15 metres high. The earlier sections on the wall are made of compacted dirt and stone. Later in the  Ming Dynasty  they used bricks. There are 7,000 watch towers, block houses for soldiers and beacons to send smoke signals. Later dynasties adopted different policies towards northern frontier defense. The   Han   (202   BC – 220   AD), the   Northern Qi   (550–574), the   Jurchen -ruled   Jin   (1115-1234), and particularly the   Ming   (1369–1644) were among those that rebuilt, re-manned, and expanded the Walls, although they rarely followed Qin's ...
