History of computer

The history of computer begins with the birth of abacus which is believed to be the first computer. It is said that Chinese invented Abacus around 4,000 years ago. It was a wooden rack which has metal rods with beads mounted on them. The beads were moved by the abacus operator according to some rules to perform arithmetic calculations Early History of Computer Since the evolution of humans, devices have been used for calculations for thousands of years. One of the earliest and well-known devices was an abacus. Then in 1822, the father of computers, Charles Babbage began developing what would be the first mechanical computer Started in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert at the Moore School of Electrical Engineering of the University of Pennsylvania. Because of its electronic, as opposed to electromechanical, technology, it is over 1,000 times faster than any previous computer

The following brief history of computing is a timeline of how computers evolved from their humble beginnings to the machines of today that surf the Internet, play games and stream multimedia in.. The history of computers goes back thousands of years with the first one being the abacus. In fact, the earliest abacus, referred to as the Sumerian abacus, dates back to roughly 2700 B.C. from the Mesopotamia region. However, Charles Babbage, the English mathematician and inventor is known as the Father of Computers The universal language in which computers carry out processor instructions originated in the 17th century in the form of the binary numerical system. Developed by German philosopher and mathematician Gottfried Wilhelm Leibniz, the system came about as a way to represent decimal numbers using only two digits: the number zero and the number one History of computing A computer might be described with deceptive simplicity as an apparatus that performs routine calculations automatically. Such a definition would owe its deceptiveness to a naive and narrow view of calculation as a strictly mathematical process The Effect of World War II 1938 * In 1938 the Polish Secret Service managed to steal an Enigma machine that was smuggled to England. * Secretly the British developed a computer named Colossus that could decipher as many as 2,000 messages per day. That computer used Vacuum tubes and was the world's first entirely digital computer

When was it invented, its history, Rohan eagerly asked. Sir Dig-a-Lot took a deep breath and answered, The first computer was a simple calculator made of a bunch of strings and beads. It was called the Abacus. It was used for simple calculations and was invented in 500 B.C. Blaise Pascal then invented a simple calculator in the year 1642. A Brief History of Computer Viruses The story of malware and the people behind it is a long and detailed one, but an important tale as well: as they say, those who do not know history are doomed to repeat it, and a better understanding of the history of viruses and malware can go a long way to helping you recognize modern threats. So let's. A Brief History of Computers. It's fascinating to see the history of computers, from the early mechanical calculating device to modern digital computer. The distinction between an age-old abacus and the modern computer seems huge, but the basic principle of doing repetitive calculations faster than human brain is still the same

C omputers truly came into their own as great inventions in the last two decades of the 20th century. But their history stretches back more than 2500 years to the abacus: a simple calculator made from beads and wires, which is still used in some parts of the world today. The difference between an ancient abacus and a modern computer seems vast, but the principle—making repeated calculations. The next major step in the history of computing was the invention of the transistor in 1947. This replaced the fragile and power hungry valves with a much smaller and more reliable component. Transistorized computers are normally referred to as 'Second Generation' and dominated the late 1950s and early 1960s History of Computer Translate. Monday, December 31, 2018. Development and History of computer What is computer? Computer is a machine used for calculation or a computation, but actually it is much more than that.,computer is an electronic device for performing arithmetic and logical operation. Or computer is a device or a flexible. Konrad Zuse created the first computing device ( called the Z1) utilizing all the parts we see today in modern computers. While it was only mechanical and used punched tape to operate, it was a big breakthrough. It was also another twist in history since the Z1 was destroyed in Germany during World War II. Zuse survived the war, though, and put.
