UNDERSTANDING COMPUTER


Computers are tools used to process the data according to the procedures that have been formulated. Computer word originally used to describe people who do the work in arithmetic calculations, with or without tools, but the meaning of this word and then transferred to the machine itself. Their origins, processing information almost exclusively related to arithmetical problems, but modern computers are used for many tasks unrelated to mathematics.

In such a definition is a tool like a slide rule, mechanical calculator types ranging from abacus, and so on, until all contemporary electronic computers. Better terms suitable for a broad sense such as "computer" is "that process information" or "information-processing system."

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 is also used as a "mechanical calculators. During World War II, the word refers to female workers of the United States and England whose work calculating artillery war path with the cash register.

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 will be considered as well as a computer.

Processing

Central Processing Unit or CPU to process the referral role, implement and deal with excessive calculation menerusi information computer system. Processing units or devices will also communicate with the device input, output and storan to implement directives related.

Input and results

Input / Output allows the computer to get information from the outside world, and put his work there, can the physical form (hardcopy) or non-physical (softcopy). There are various kinds of input devices ie keyboard, mouse. And output devices for example, monitors and disk drives, to the more unusual such as a webcam (web camera, printer, scanner, and so on.

computer parts

Computer consists of 2 major parts of the software (the software) and hardware (hardware).

Hardware:
* Processor or CPU as the data processing unit
* Memory RAM, which store data temporarily
* Hard drive, semi-permanent storage medium
* Input device, the media used to enter data to be processed by the CPU, such as mice, keyboards, and tablets
* Output device, the media used to display the CPU processing the output results, such as monitors and printers

Software:
* The operating system
Basic programs on a computer that connects users with computer hardware. The operating system used is Linux, Windows, and Mac OS. Operating system tasks, including (but not only) controls the execution of programs on it, coordination of input, output, processing, memory, and software installation.
* Computer programs
Additional applications are installed in accordance with the operating system
