knowledge about the distribution of computer

Definition

Computer comes from the latin language which means computare calculate. Because the extent of computer science, experts and researchers in a slightly different terminology defines computer.

* According to Hamacher [1], the engine computer is fast and electronic information can receive a digital input, and processing in accordance with programs stored in memory, and produce output in form of information.
* According to Blissmer [2], the computer is a tool that elektonika able to do some tasks as follows:
- Receive input
- Process the input according to the earlier program
- Keep the commandments and the results from the processing
- Output in the form of providing information
* The Fuori [3] argued that the computer is a data processor that can perform large calculations quickly, including the calculation of arithmetic and logic operations, without intervention from humans.

To realize the concept as a computer data processing to produce an information, the required computer system (computer system) that consists of hardware elements, software and brainware. The three elements of the computer system must be interconnected and form a unity. Hardware will not work without the software, when, as vice versa. And no useful when they are not human (brainware) that operates and controls.

1. Hardware or Hardware: equipment that is physically visible and can be held.
2. Software or Software: programs that include instructions / commands to perform data processing.
3. Brainware: men who control and operate the computer system.

Computer classification

Literature on the computer to computer ranking based on three things: the data processed, use, capacity / size, and generation.

Based on the Data Calculated

1. Analog computer
2. Digital computer
3. Hybrid computer
