Computer :
Computer and computer sound means we are more or less all know. Then we remind everyone again. The word comes from the Greek word komonpout the computer. The literal meaning of komonpout account or counted. The meaning of the word count, and computer equipment. Gankainatar or computer is a machine which follow mathematical calculations related to very fast. But at present, and not just the computer counting machine. Computer is a device that takes information and analysis through various processes. In Bangladesh, the first computer came in 1964.
The world's oldest computer
Abacus
The number of people in ancient times to oyster, gravel, a rope used git, etc. Later calculations using different techniques and machine and Abacus counting machine is an ancient computer as the first machine in history. In other words, from the computer history abacus shuvatura. It was discovered in 2400 BC, Babylon. Abacus frame decoration moves to change the space calculation device. BC 450/500 BC in Egypt or China abacus as a counting machine.
In 1616 the mathematician John Napier of Scotland, so printing with corrections/marks or rods. These are known as Napier's bones.
1642 Blaise Pascal in the 19-year-old French fertilizer the first mechanical calculator. He employed the help of the gear wheel or the method of subtraction. In 1671, the German mathematician gotferide von loibners Pascal machine on the basis of the wheel and rods using multiplication and Division of the definition more advanced mechanical calculator Teri. He has removed the name of the device the device. The theoretical side of the device with good mechanical problem becomes popular.
In 1820 after Tomas removed the device removes the difficulty of lohabnaser popular device. At the beginning of the 19th century, the construction of the modern idea of a device first used by Babbage. He named it dorfarenes engine. The dorfarenes engine in 1833 while working with more advanced and in the name of universal engine aranal is a machine concept. But there is no lack of the necessary equipment and money he could to finish the job.
Enrothertara mekanazam:
In the summer of 1900. In April, a group of Greek sponge divers ' lazy to plunge to a place near the Greek island of "enrothertara". Their mission under water near the island brought up sponge from the market. This dream never did not think the Group of divers that they were going to be the oldest of the world of computer users. Because he still is making the computer originally. Ordinary people is even not computer science involved all knew about the machine.
They gave him 148 feet 45 meters of the sea, or dive into the deep. After going down the water they had seen in the darkness might Dim a lot of the older part of a ship. They came up in the excitement of discovery. All of the party. Everyone went down to dip again, sure that a lot of the old ship is a ship. The idea of bringing up their sponge. The party began with an old ship khattakhat all together. The ship's name is "enrothertara rhak" of the ship. Dive team began to lift slowly sinking ship old equipment. Some very old bronze, marble statues, pottery, glass, jewellery, coins, etc. But such items when using some of them.
They gave everything to save Athens ' National Museum of arscolzi in which the scientist works with these can enrich civilization, the history behind these objects can bring forth. Diver rescued from ship to stuff the trout group, with bronze base damage, "How are aljor random isolated delivered some daasodzala wheel. All the things in the Museum are drawn 2 years. A group of researchers and staff of the Museum's pieces began to come together by isolated parts. A member of the group that arekolzessolot bhelerus saitseic still did not know how long that one key from the darkness of ancient history to the discovery.
Saitseic, rubbing the stuff felt pieces one piece with another piece trying to find something. He noticed a wheel inside a rock. At first he thought it was a "esrotteromo time clock or can be something other than advanced, but other sinertorsitra disapproval. Impossible, it can't be. Because this is a complex machine like this how people before.
Already coming out that this ship roughly the time of the birth of Jesus and almost 1900 years old. They took the wheel of the guess thing more than age. They had an idea this thing (), born at least 100-150 years old. This is a pretty old bronze pieces could not shake the team researchers. The most ancient of the world do not know that they are going to discover the computer just came back from.
Professor price stand the pieces together that 2000 years ago the ancient ruined the computer showed the people of this world, make again
"Look, what was coming a year 2000 computer:
The ancient Greek island of enrothertara scientist used this device to them what it is not, however, give a name. Professor of history of the world to discover the price of mekanakerakel was given the name "enrothertara mekanazam" of the computer.
Today's modern electronic computer to the computer is probably nothing but 2200 years ago, man is designed with computers, space research has always been one of those mekano, locate stars with their calendars, even four years after the The Greek Olympiad held at the time and it is by this computer. Today, in front of an electronic computer in 2015 while working on these ideas.
Binary logic
Gottfried Wilhelm loibners in 1703 his writing binary number system, a formal mathematical sense logic improvements. In his system, and zero represents the quality and truth. But in 1854, George and repeating its mathematically established a complete system of computational processes with Boolean algebra to be honest more than a century.
During this time the binary pattern was first powered by a mechanical device invented. The industrial revolution brought forward in the mechanization of work. In 1801 Joseph Mary jarjakuzarid-gut punch card control. A hole where a binary one and a spot card a binary zero. It was far from a computer jarjakurer looms, but it could lead to machines powered by binary systems.
Computers & computing one of the foundation stone :
In 1926. 14-year-old Allan tarwar sherborran, the first class of the school. The same day, the UK's general strike. But go to school taurs. Hehe nachrbanida. In the end, riding his bicycle alone had 97 kilometres to school near by. :O
Sherborran school usually had language, literature, philosophy, emphasis, arts etc. But there was no mind. Tarwar was really abysmal math and science. Therefore, the school's head teacher wrote a letter to his father tarwar are saying, tarwar the possibility of a much larger future scientist and mathematician. So sherbarran tarwar and samajashepanshould not be used.
In 1936 after 10 years of Alan taurs "in a special device name device taurs discovered. It is not a material device, but nothing written in pen and paper policy. This is one of the most modern computer and computing devices are taurs foundationstone. The development of the modern electronic computer, greatly inspired by taurs device. Alan in 1954 at the age of just 42 with cyanide taurs Apple died after eating. However, it is in the life of solballaj computer science is rich in different ways. Alan torur is the father of artificial intelligence and computer science.
Taurs award:
New York-based world's ancient computer Association Association for computing (ACM) of computer science in 1966 for paultry industry producer Alan tarwar name of prestigious computer science Award launched ' taurs Award ". Civilization and people influenced by fast computer run all the discovery of science and gobeshanakari for each year the award is given to taurs. Taurs award in computer science tradition, the far-reaching impact of the award, the award-winning taurs taurs unique creativity and overall acceptance worldwide because it has been described as the ' Nobel ' of the computer. The financial value of this award two million 50 thousand dollars.
In 1966, the year the launch of the prize award taurs was awarded the American computer scientist Alan Perlis. His great contribution to the development of programming languages and kamaspaila for this prize. Famous programming languages he named arjalagal, a co-inventor. "If you want to also learn computer and computers can be taught anything" — the concept and theory of the pioneers of artificial intelligence provider morjakkarothar taurs Prize in 1971. The father of the c programming language and the UNIX operating system with the creator Dennis Ritchie taurs award in 1983. Francis is Allen was one of the first women who was awarded the prize in taurs. In 2006 us computer scientist and computer kamaspaila performance brididhavisath for research taurs prize. Another woman, Barbara taurs Prize in 2008 lorskov. Computer parogorum advanced school: his role in the development of object oriented programming and advanced software for architectural research award. He saweliu and two programming languages and associated argas. Among the first Asian taurs Prize Indian computer scientist Raja Gopal Raj Reddy. Large scale application of artificial intelligence, artificial intelligence, and technical framework of the commercial aspects of artificial intelligence research in 1994 for taurs prize. In his own country in 2001 Reddy was awarded Padma Bhushan title. Last year, the prize was awarded $ taurs computer scientist Leslie g. valiant. Machine learning-theory, parallel computing, and other subjects important for the prize. Over the past 45 years, a total of 57 people were awarded this prize in computer scientist.
In fact, mechanical and electronic counting with the help of a computer that can be related to, with the help of the machine and its all taurs are possible. But in reality it is not with the help of a computer implementation of a lot and with the help of the machine as possible. taurs Around the world, computer scientists are travelling to understand better the limitations of real computing taurs device. And taurs Award and computer scientists reveal new horizons real computing removes the limitation on who ever is motivations.
From the past are currently computer:
From the past to the current computer takes over. Modern computer scheme created by British mathematician
In 1822 he discovered "dorfarenes engine" because of some problems could not be created. In 1833 he again after many previous gannakaro device a centralised feel. Because of this need to think of a device called "anjanaltorkal machine". It's so he can finish. The machine design is based on today's computers. This is why he is called the father of the father or the computer. After Lady adraja agasherta, Frank bonediun, Charles Babbage, with many more move forward in the work of.
Charles Babbage in 1887: Dr. harmahan halereth "United States Census of electorato mekanakerakel system parachaqar to use a device discovery. This would be a quick census work. In 1896 he developed for "halereth tebulateras machine company" in the name of a company. Subsequently, several companies are established. These companies are creating together is a famous institution "international business machines Corporation or the current IBM.
In 1986 the United States Pennsylvania University Professor: Dr. John mousler and his students ' first generation ' match akernod made digital presper computer ENIAC. It was very highly and was nearly 30 tons of weight. This 5000 per second to subtraction.
In 1946, the Hungarian mathematician John von Neumann stored program concept was invented. He is the first computer "information and" reserved parking. This concept is based on EDSAC in Cambridge University Professor by the name of morosh wilucksh 1946 the first automatic electronic digital computer
Von narjhrmain policy before creating work on ENIAC's creators ' EDSAC, John mousele, and j. The name is used to create computer ENIAC "presper Eckert. They were busy creating a company in which the computer is to create delay. EDVAC in 1950.
Then ' mousele ' and ' j. Presper Eckert in their company "in March 1951 UNIVAC-1. It is the first commercial electronic computer created. This Crystal diode switch and vaizakuzalem tube circuits used. This is aread, write and count information. The first UNIVAC-1 is the latest Census Bureau Of the United States, has been in Office, the second air force, the third army map service in the Office. In 1953 a IBM701 commercial computer built by IBM. At this time the program was invented binary language.
In 1948 due to absharker tranjas bulb tarsanjaslatar is used instead. As a result of computer use it slowly in size small. This was developed from the earlier computers, fast dynamic and sustainable. Datmauth of the United States in 1964, two professors J. G. Kemeny and Kurtz in the name Tomas has a basic program written. It is easy to write a program in highly. Which is very popular.
Tarsanjaslatar IC or Integrated Circuit was invented after the discovery. A small part of Silicon more tarsanjaslatar together it. I use kamarpouter, its very small size increased with the quality and speed of work is faster.
