About Computers

 

       Computers are tools used to process the information 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 such a definition 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 "that process information" or "information processing systems."

       The term computer (computer) comes from the Latin meaning computare count. Computers have a very broad meaning and is different for different people. Here is the definition of a computer that is gathered from many computer books.

       According to the Annual Computer (Robert H. Blissmer), the computer is an electronic device capable of performing several tasks as follows:
* Receive input
* Processing the input was in accordance with programmnya
* Keep the commandments and the results of processing
* Provide output in the form of information

      According to the Computer Today (Donald H. Sanders), a computer is an electronic system to manipulate data quickly and accurately as well as designed and organized to automatically receive and store input data, processes it and produces an output under the supervision of a step-by-step program instructions that stored in memory (stored program).

       According to the book Computer Organization (VC Hamacher, ZG Vranesic. SG Zaky), the computer is a fast electronic calculating machine can accept digital input information, process it in accordance with a program stored in memory (stored programs) and generate output information.
       According to the book Introduction To The Computer, The Tool Of Busines (William M. Fouri), the computer is a data processing (data processor) that can do big and fast calculations, including calculations of arithmetic or logic operations, without intervention from humans operate during processing.
       According to the book Introduction To Computers (Gordon B. Davis), a computer is a special type of computing device that has certain properties that must be.

       Of the several definitions derived from a variety of books, it can be concluded that the computer is:
* Electronic Equipment
* Can accept input data
* Can process the data
* Can provide information
* Using a program stored in computer memory (stored program)
* Can save the program and the results of processing
* Works automatically
       While the program is called with a set of detailed instructions or commands that have been prepared so that the computer can perform its functions in a way that was certain.

       The word "Computer" Over the years there have been several slightly different meanings to the word 'computer', and several different words for things we now usually called a computer. Eg "computer" once commonly used to mean hiring someone to perform arithmetic calculations, with or without engine assist. 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 are also to "mechanical calculators". During World War II, the word refers to the U.S. and British women workers whose jobs account for a large war artillery road with such machines.

       Charles Babbage designed one of the first calculating machine called the Analytical Engine, but due to technological problems are not built in his lifetime. A variety of simple mechanical devices such as a slide rule kind have also been called a computer. In some cases they were referred to as "analog computer", as they represent numbers by continuous physical quantities rather than in addition to the binary digits are different. What are now called "computers" were once commonly called "digital computers" to distinguish them from these other devices (which are 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 Italian, the computer is "calcolatore", a calculator, to emphasize that computational logic behind using such sorting. In Swedish, a computer is called "dator" from "data". Or at least the 1950's, they are called "matematikmaskin" (math engines). In Chinese, a computer called "deen lake" or an "electric brain". In English, in other words and phrases have been used, such as "data processing machines".
