What Hardware

A hardware component that is assembled in such a way as to achieve the desired goal, given the hardware can operate when the electric current.

Hardware arrangement can be called a string of highly structured electronic power supply voltage is only recognize both positive and negative is digitally known as 1 and 0, the Hardware only recognize the numbers 1 and 0. To interact with the hardware just by using the numbers 1 and 0. Programming language that recognize the numbers 1 and 0 are called machine language.

Hardware inside a computer device itself can be subdivided into several parts according to their needs and by function.

1.  According to the requirement.
   
   • Main Hardware.
     Hardware is in use depends accordance use and is still divided into 2 parts.
     Example: Motherboard, RAM, Power Supply, Notebook, Processor, VGA Card, Keyboard, Monitor.
   • Additional Hardware.The computer can still run without the presence of additional hardware but in the presence of additional hardware will add power to atai computer skills and more beneficial to users.
     Example: Mouse, LAN Card, Bluetooth Card, WebCam, Wi fi card, USB modem, stick
     
2.  According to the function.
   Apart from the needs of the wearer's own hardware hardware functions can be divided into terms of functions, namely: Input Devices, Processing Devices, Exit Devices.
   • Input Devices.input device is a device used to insert images, text, sound, video into the computer then processed and deliver results as expected. Based on the type inputannya input devices can be divided into:
     - Press the input devices, eg keyboards.
     - Sliding input device, eg mouse.
     - A voice input device, eg a microphone.
     - Video input devices, eg camera.
   • Device Processing.processing device is a device used to process the input device input.
     Based on the processing functions can be divided into:
     - The main processing unit (CPU).
     - Logic and arithmetic processing unit.
     - Processing Unit temporary (RAM).
   • Exit Devices. The device displays the results of a given output device processors. The device outputs can be grouped into two main parts:
     - Physical output devices, eg printers.
     - Non-physical output device, for example: the monitor.
