History of the Computer - Computers and Technology

volume and the use of computers in the world are so great, they have become more difficult to ignore. Computers seem to us in so many ways that many times, we do not see them as they actually are. People connected to the computer when they bought their morning coffee in the vending machine. As they drove to work, traffic lights that bothers us so often are controlled by computers in an attempt to speed travel. To accept it or not, the computer has invaded our lives.

origin and roots of the computer is started like many other inventions and technology in the past. They have evolved from relatively simple ideas or a plan designed to help carry out the functions easier and faster. The first basic type of computers are designed to do just that, to count!. They perform basic mathematical functions such as multiplication, division and displays the results in different methods. Let the computer displays the results in the binary representation of electronic valves. Binary means using only ones and zeros in this way, lit lamps represent himself and lit lamps represent nule.Ironija this is that people need to do extra math translate binary to decimal to be read to the user.

One of the first computer was called ENIAC. It was huge, almost monstrous size of a standard rail car. It contains electronic tubes, heavy gauge wiring, angle iron, and knife switches just to name a few components. It becomes difficult to believe that computers have evolved into suitcase sized micro-computers in the 1990s.

Computers eventually evolved into a less archaic looking device at the end of 1960th Their size is reduced to that of small cars, and they are pieces of data processing at a faster rate than older models. Most computers at that time were called "mainframe" due to the fact that many computers are connected to perform certain funkcije.Primarni users of this type of computers are military agencies and large corporations such as Bell, AT & T, General Electric, and Boeing. Organizations such as these funds to afford such technology. However, the operation of these computers requires comprehensive intelligence and manpower resursa.Prosječna person can not be fathomed trying to act and to use these processors millions of dollars.

United States attributed the title of the pioneering computer. It was not until the early 1970s that nations such as Japan and Great Britain began to use technology for their own development computers. This has resulted in newer and smaller components računala.Korištenje and work computer has developed into a form that people of average intelligence could handle and manipulate without much difficulty. When the economies of other nations began to compete with the United States, the computer industry expanded at a great rate. Prices dropped dramatically, and computers became more accessible to the average household.

As the invention of the wheel, the computer is here stay.The operation and use of computers in our current era of the 1990s has become so easy and simple that we could perhaps take too much for granted. Almost all use the company requires some form of training or education. Many people say that is a precursor to the computer typewriter stroju.Pisaći machine definitely need training and experience to work in a usable and effective level. Children are taught basic computer skills in the classroom to prepare them for the future evolution of the computer age.

history of computers began around 2000 years ago, the birth of the abacus, a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around in accordance with the rules of the program memorized by the user, all regular arithmetic problems can be done. Another important invention around the same time was the astrolabe, used for navigation.

Blaise Pascal is usually credited with building the first digital computer in the 1642nd It added numbers entered with dials and was made to his father, a publican. In 1671, Gottfried Wilhelm von Leibniz invented a computer that was built in 1694. It might add, and after changing some things around, multiply. Leibnitz invented a special stopped gear mechanism for introducing addend digits, and it is still used.

prototypes by Pascal and Leibniz were not used in many places, and is considered weird until a little more than a century later, when Tom Colmar (AKA Charles Xavier Thomas) created the first successful mechanical calculator that could add, subtraction, multiplication, and dijeljenje.Puno better desktop calculators by many inventors followed, so that around 1890, a number of improvements include: the accumulation of partial results, storage and automatic reentry of past results (memory), and print results. Each of these required manual installation. These improvements are mainly for business users, not for science.

While Tom Colmar developing desktop calculator, a number of very interesting developments in computers began in Cambridge, England, Charles Babbage (of which computer store "Babbages" is called), professor of mathematics. In 1812, Babbage realized that many long calculations, especially those that are required to make mathematical tables, these are actually a series of predictable actions that constantly repeats itself. Since it is suspected that it should be possible to do this automatically. He began to design an automatic mechanical calculating machine, which he called the difference engine. Until 1822, he had a working model to show. Financial assistance from the British government to accomplish and started making Babbage difference engine in the 1823rd It was intended to be steam powered and fully automatic, including the printing of the result table and commanded by a fixed instruction program.

The difference engine, although it has limited adaptability and applicability, was really a great improvement. Babbage continued to work on it the next 10 years, but in 1833 he lost interest because he thought that a better idea of what the building will now be called a general-purpose, fully program-controlled, automatic mechanical digital computer. Babbage Analytical motora.Ideja called the idea of this design showed a lot of predictions, although it can not be appreciated until a full century later.

plans for this engine required an identical decimal computer operating on the number of 50 decimal digits (or words) and has a storage capacity (memory) brojki.Ugrađeni than 1,000 such operations were to include everything a modern general, -. The purpose of the computer should be, even the all important Conditional ability to control the transmission which will allow commands to be executed in any order, not just the order in which they are programmed

As people can see, it is quite a large amount of intelligence and courage to come until the 1990s style and computer use. People have speculated that the natural evolution of computers in society and take them for granted. Just as people have learned to drive a car, it also takes skill and learning to use a computer.

Computers in society have become difficult to understand. Exactly what they do and what actions are performed are very dependent on the type of computer. To say a person has had a typical computer is not necessarily able to narrow down just what the computer. Computer styles and types of covered so many different functions and activities, so it is difficult to name them svih.Izvorni PC 1940 was not easy to define their purpose, when they were first invented. They are primarily performed mathematical functions many times faster than any person can be calculated. However, the evolution of computers has created many styles and types that are largely dependent on well-defined goal.

computers of the 1990s roughly fell into three groups consisting of mainframes, networking units and personal computers. Mainframe computers were extremely large modules and was able to process and store vast amounts of data in the form of numbers and words. Mainframe computers are the first types developed in 1940. Users of this type of computers ranging from banking companies, large corporations and government agencies. They are usually very expensive in price, but designed to last at least five to ten years. They also need well-trained and experienced manpower for operation and maintenance. Larry Wulforst, in his book Breakthrough in computer time, describes the old mainframe in the 1940s compared with those from the 1990s, speculates, "... unlike the sound sputtering engine starts first flights in the Wright brothers at Kitty Hawk and the roar of powerful engines Cape Canaveral on the springboard. "End of first part.
