The computer comes from the Latin computare implying count. Because of the extent of arable fields of computer science, experts and researchers differ slightly in defining termininologi computer.
According to Hamacher [1], a computer is a fast electronic calculating machine and can accept digital input information, and then process it in accordance with a program stored in the memory, and generate output information.
According Blissmer [2], the computer is an electronic device capable of performing multiple tasks as follows:
- Receive input
- Process the input earlier in accordance with its program
- Keep the commandments and the result of processing
- Provide output in the form of information
Sedangan Fuori [3] found that a computer is a data processor that can perform large calculations quickly, including arithmetic and logic operations, without intervention from humans.
To realize the concept of the computer as a data processor to generate the information, it requires a computer system (computer system) whose elements consist of hardware, software and brainware. The three elements of a computer system must be interconnected and form a unity. Hardware will not work if no software, and vice versa. And both are not useful when there is no human (brainware) who operate and control.
Hardware or Hardware: equipment that is physically visible and can djamah.
Software or Software: Software that contains the instructions / commands to perform data processing.
Brainware: people who operate and control computer systems.
Classification of Computers
Recent literature on computer doing computer classification based tigal things: data processing, utilization, capacity / size, and generation.
Under The Processed Data
Analog Computer
Digital Computer
Hybrid Computers
Based on its consumer
Computers For Specific Purposes (Special Purpose Computer)
Computers for General Purpose (General Purpose Computer)
Based on the capacity and size
Micro Computer (Micro Computer)
Computer Mini (Mini Computer)
Small Computer (Small Computer)
Computer Medium (Medium Computer)
