- Provide an output in the form of information

• without human intervention, can arithmetic and logic operations, you can quickly carry out large-scale calculations, Sedangan FUORI [3] The computer was a data processor.

Such a data processor for generating information to achieve the concept of the computer, the element is required (PC) is a computer system that is composed of BrainWare hardware, and software. It is necessary to have a unit three elements of a computer system is connected. I do not work when there is no vice versa hardware, software, and. Work, as the control (brains) does not exist, it is not useful either man.

2. The software / command instructions to perform data includes: software or software.

3. Brainware: the operation of a computer system, control subjects.
