Computer Basic Engine capable of running the instructions to perform operations on data. Features that differentiate from the computer is the ability to save your own instructions. This capability allows a computer to perform various operations without the need for someone to enter a new



instruction each time. Computers are made of modern high-speed electronic components that enable computers to perform thousands of operations every second.

Philosophy

One of the components is able to carry out a sequence of operations in the set. The definition of operating a program called. Analog to manipulate a computer by continuously variable physical computations, such as voltage and time. Digital computers operate in discrete quantities, most often described as' on-off ', which indicates whether the value of a variable is a binary 0 or 1. Figures and information which is then represented by the binary system. Philosophically excitement generated by the computer which has been exploring the mental operations that represent computations as well. See also artificial intelligence, Chinese room, connectionism, Turing machines, von Neumann machines.



A device that receives, processes, and presents the information. The two basic types of computer analog and digital. Although generally not regarded as such, the most common computer a simple mechanical analog computer, in which gears, levers, ratchets, and pawls perform mathematical operations-for example, the speed and watt hour meter (spending that is used to measure the use of electricity). The general public has become more aware of the digital computer with a fast proliferation of hand-held calculator and a large variety of intelligent devices and especially with exposure to the Internet and World Wide Web. See also the calculator, Internet, World Wide Web.

Computers that use the analog input proportional to the instantaneous value of the variable quantity, combining entries specified in this way, and produced a varied output of the input functions and processes. Output is then displayed or connected to another device to cause action, as in the case of speed governor or other control devices. Small electronic analog computers are often used as a component in the control system. If the analog computer is built for one purpose only, the term is a special-purpose electronic analog computer. Analog computers in the key concepts involve special versus general-purpose computer design, and technology used to build the computer itself, mechanical or electronic. See also Analog computer.

Instead, the digital computer using symbolic representations of variables. Arithmetic unit that was built to follow the rules one (or more) number system. Furthermore, using a digital computer each discrete state the number of digits to represent the system chosen. Digital computer can easily store and manipulate numbers, letters, pictures, sound, pictures or information symbolically represented by the code. Through the use of the stored program, digital computer achieve a degree of flexibility unequaled by any other computer or data processing device.

Coming from a relatively cheap and easily available computers, and a combination of computer and communications, such as using the network, have dramatically expanded computer applications. The most common applications are now possible and the word text, followed by electronic mail. See also electronic mail;-Local Area Network; Microcomputer; Word processing.

Computers began to meet obstructions imposed by light speed to reach high speed. This is the research and development in the field of parallel computer (in order to achieve more than by serial parallel computation) and distributed computers (taking advantage of a network connection is working to spread around, so it reaches more parallelism). Will continue to demand more processing power has caused significant changes in computer hardware and software architecture, to improve the speed and the basic operation to reduce the overall processing time.

Computer

An electronic device that stores and manipulates information. It differs from a calculator in being able to store a program and to store and retrieve information in its memory without human help.

An electronic device that stores and manipulates information. He was different from the calculator because it can save the program and to store and retrieve information in memory without human assistance.

Programmable computer that can store, retrieve, and process data. Today computers have at least one CPU to the calculation and include main memory, control unit, arithmetic and logic unit. The more, the computer contains a special graphics processor, which is dedicated to the memory to handle the complex computations needed to display images, such as three-dimensional simulation and for the game. Auxiliary data is usually provided by the internal hard disk and may be supplemented by other media such as floppy disks or CD-ROM. Peripheral equipment includes input device (for example, keyboard, mouse) and output devices (eg, monitor, printer), and the circuitry and the cable that connects all the components. Generation of computer technology characterized by them. The first generation of digital computers, mostly developed in the United States after World War II, used vacuum tubes and large. Second generation, introduced c. 1960, and transistors have been used first commercially successful computer. Third-generation computer (the end of the 1960s and 1970s) is characterized by miniaturization of components and integrated circuits. The microprocessor chip, introduced in 1974, defines the fourth-generation computer.
