definition and types of computer hardware

Hardware / Hardware is a tool / object that we can see, touch, grasp and has a specific function. Physically, there may be. There is a shape. Hardware device consists of 3 types, namely: 1. Input device (input device) Input device used to enter data, either text, photos, and pictures into komputer.Contoh input devices such as keyboards, mouse, light-pen, scanner, and so forth. 2. output device (output device) output device used for collecting and producing data released, such as monitors and printers. 3. Data processing device (processor) Data processing device used to process data data.Pengolah includes a central processing unit (CPU or Central Processing Unit) and also microprocessors.


Based on its function, the computer hardware is divided into:
1. divice input (input units)
2. Process devices (processing units)
3. Output devices (unit output)
4. Backing Storage (storage unit)
5. Peripherals (additional unit)


Various kinds of hardware (hardware):
1. CPU (Central Processing Unit)
