Definition of General Computer

Definition of General ComputerComputer or Computer is a tool used to process the data according to procedures that have been formulated. Word computer originally used to describe people who perkerjaannya perform arithmetic calculations, with or without a walker, but the meaning of this word is then transferred to the machine itself. Originally, the processing of information is almost exclusively related to arithmetical problems, but modern computers are used for many tasks unrelated to mathematics.In the sense that there are tools such as slide rules, mechanical calculators types ranging from abacus and so on, until all the contemporary electronic computers. The term better suited for a broad sense such as "computer" is "information processing" or "information processing systems." Over the years there have been several different meanings in the word "computer", and several different words are now called called a computer.The word computer once commonly used to define people who perform arithmetic calculations, with or without auxiliary engine. According to the Barnhart Concise Dictionary of Etymology, the word is used in English in 1646 as the word for "people who count" then before 1897 are also used as a "mechanical calculators". During World War II, the word refers to the workers of the United States and British women who work to calculate the path of artillery warfare with the machine count.Charles Babbage designed one of the first calculating machine called the analytical engine. In addition, a variety of simple machine tools such as slide rule also has to be said as a computer.Nevertheless, the above definition includes many specialized tools that can only account for one or several functions. When considering modern computers, their most important properties that distinguish them from earlier computing devices is that, with proper programming, any computer can emulate any nature (although limited by storage capacity and speed are different), and, indeed believed that the machine can now mimic the computing devices we invent the future (although slower). In a sense, these limits is a useful test for the computer to recognize "common purpose" of special-purpose devices early. The definition of "general intent" can be formulated into a requirement that a machine must be able to emulate a universal Turing machine. Machines that this definition is known as a Turing-complete, and that they first appeared in 1940 in the midst of developments around the world.

How computers workWhile the technologies used in digital computers have changed dramatically since the first computers in the 1940s (see History of the hardware count for more detail), most still use the von Neumann architecture, which was proposed in the early 1940s by John von Neumann .Von Neumann architecture describes a computer with four main sections: Arithmetic and Logic Unit (ALU), control unit, memory, and input and output devices (collectively termed I / O). This section is connected by a wire beam, "bus"
