Computer

Computer term has a broad meaning and differ for each person. The term computer (computer) is taken from the Latin word meaning computare count (to compute or to reckon).According Blissmer (1985), a computer is an electronic device capable of performing multiple tasks, which receive input, process the input in accordance with the instructions, keep the commandments, and the results of its processing, and provides output in the form of information.Meanwhile, according to Sanders (1985), a computer is an electronic system to manipulate data quickly and accurately as well as designed and organized in order to automatically receive and store input data, processes it, and produces output based on the instructions that have been stored in memory. And many more experts are trying to define it differently on the computer. However, in essence it can be concluded that the computer isan electronic device that can accept input, process the input, provide information, using a program stored in the computer's memory, to store programs and results processing, and works automatically.From the definition, there are three important terms, the input (data), data processing, and information (output). Data processing using a computer known as electronic data processing (EDP) or elecronic the data processing (EDP). Data is a collection of events that raised a fact (fact), to the form of numbers, letters, special symbols, or a combination of all three. Data still not able to tell a lot more that needs to be processed further.Data processing is a process of manipulation of data into a form that is more useful and more means, in the form of an information. Thus, information is the result of a data processing activities that provide a more meaningful form of a fact. Therefore, electronic data processing is the process of manipulation of data into a more meaningful form of an information by using an electronic device, the computer.

Or also Computers are tools used to process information according to procedures that have been formulated. Computer word was originally used to describe people who perkerjaannya perform arithmetic calculations, with or without the tools, but the meaning of this word is then transferred to the machine itself. Origins, processing information almost exclusively related to arithmetical problems, but modern computers are used for many tasks unrelated to mathematics.In such a definition there are tools such as slide rules, mechanical calculators types ranging from abacus and so on, until all contemporary electronic computers. The term better suited for a broad sense as "computer" is "that process information" or "information processing systems."The term computer (computer) is derived from the Latin word meaning computare count. Computer has a very broad meaning and is different for different people. Here is the definition of computer is obtained from several computer books.According to the Annual Computer (Robert H.Blissmer), a computer is an electronic device capable of performing multiple tasks as follows:* Receive input* Process input earlier in accordance with its program* Keep the commandments and results from processing* Provides output in the form of informationAccording to the book Computer Today (Donald H.Sanders), a computer is an electronic system to manipulate data quickly and accurately as well as designed and organized in order to automatically receive and store data input, processing and output under the supervision of a step-by-step instructions that program stored in memory (stored program).According to the book Computer Organization (VC Hamacher, ZG Vranesic. Zaky SG), a computer is a fast electronic calculating machine that can receive digital input information, process it in accordance with a program stored in memory (stored program) and generate output information.According to the book Introduction To The Computer, The Tool Of Busines (William M.Fouri), a computer is a data processing (data processor) that can perform large calculations and fast, including large arithmetic or logic operations, without the intervention of humans operate during processing.According to the book Introduction to Computers (Gordon B. Davis), a special type of computer is a calculator tool that has certain definite properties.From the definition obtained from a variety of books, it can be concluded that the computer is:* Electronic Equipment* Be able to accept data input* Can process data* Can provide information* Using a program stored in the computer memory (stored program)* Can store the processing program and results* Works automaticallyWhile the program is called with a set of detailed instructions or orders which has been prepared so that the computer can perform its functions in a way that is certain.The word "Computer"Over the years there have been several quite different meanings to the word 'computer', and several different words for things we now usually call a computer.For example, "computer" is commonly used to mean a person employed to perform arithmetic calculations, with or without mechanical aids. According to the Barnhart Concise Dictionary of Etymology, the word is used in English in 1646 as the word for "people who count" and then before 1897 as well as to "mechanical calculators". During World War II, the word refers to the U.S. and British women workers whose jobs take into account the great war artillery with such machines.Charles Babbage designed one of the first calculating machine called the Analytical Engine, but because the problem is not technology made her life. Various machine tools as simple as a good slide rule also called computers. In some cases they are referred to as a "analog computer", as they symbolize numbers by continuous physical quantities rather than in addition to discrete binary digits. What are now called "computers" were once commonly called "digital computer" to distinguish them from the other tool (which is still used in the field of analog signal processing, for example).In the thinking of another word for computer, it is observed that prices in other languages ​​chosen words do not always have the same literal meaning as the English word. In French for example, the word is "ordinateur", which means roughly "organizer", or "sorting machine". In the Spanish used the word "ordenador", with the same meaning, although in some countries they use anglicism computadora. In the Italian language, the computer is "calcolatore", calculator, pressed behind the use of computational logic like sorting. In Swedish, the computer called "dator" from "data". Or at least in the 1950s, they were called "matematikmaskin" (math engines). In Chinese, a computer called "deen nau" or an "electric brain". In English, words and phrases have been used, such as "data processing machines".
