The Hardware

The Hardware (Hardware)

Hardware computer (hardware) are all parts of the physical computer, and be with the data residing in or who operate in it, and be with Perangakat (software) that provides instructions for Hardware in completing its tasks.
Limitation of the hardware and software will be a little blurry when we speak about firmware, because this firmware is software that "made" into the hardware. Firmware is the area of computer science and computer engineering, which is rarely recognized by the general user
Types of Hadrware

1. Printer
Epson brand inkjet printer
Printer or printer is a tool that displays the data in the form of prints, such as text and pictures / graphs, on paper. The printer is usually divided into several parts, the picker as a tool to take paper from the tray. Tray is the place to put papers. Ink or toner is indeed devices, because there is something called a toner or ink used to write on paper. The difference is the ink and toner difference system; laser toner or heating needs, while inkjet ink or do not need heating, cleaning or cleaning only the print-head printer.
There is also a flexible cable to allow signals from the processor to the printer ink or toner. This cable is thin and flexible, yet strong. On the back of the printer is usually a parallel port or USB connector to the computer.
Printer modem is a powerful tool. Perkakasan electronic printing is in a perkakasan with the electronic computer which is in itself. Have any type of printing that is the type of 6-Dot Matrix, Daisy Wheel type, the type of Ink-Jet / Bubble Jet type, chain type, type, and type of Laser Drum
2. SPEAKER (speaker)
In each of the sound system, determining the quality of sound depends on the speaker. Recording the best, is coded into the tool storage of high quality, and played with a deck and the top-class sound, the only result will be ugly sound when the speaker is associated with low quality. On the speaker system is a component that carries electronic signals, store them in CDs, tapes, and DVDs, and return it to the actual vote in the form that we can hear. In this article, will be explained how a speaker to do the process. It also will be discussed why the speakers are designed different and how these differences cause the different effects of the same quality. Speaker is an incredible technology that provides a very large impact on our culture. But besides all that, the speakers actually is just a tool that is very simple.


Speaker for television
But basically, an engine is a speaker end, opposite from the microphone. Speaker to bring electrical signals and change them back into vibration to create sound waves. Speaker of the vibration is almost the same as that generated by a microphone that is coded and recorded on tape, CD, LP, and others. Speaker traditional process of doing this by using one or more drivers.
List of loudspeaker that is generally known in Indonesia;
BMB * Altec Lansing
* Creative Pioneer
Visioneer * Sonic Gear
Logitech Marantz *
Kenwood Genius *
Delta * JBL
Simbadda
3.OLED

OLED Display Screen
Organic Light-Emitting diode (OLED) or light dioda is an organic semiconductor as a light radiator made from organic layer. OLED technology is used in elektroluminensi, as in the application screen or sensor. Flexible technology is popular with ketipisannya the reach of less than 1 mm.
Background OLED technology, scientists found by Eastman Kodak Company, Dr. Ching W. Tang in 1979. Research in Indonesia on this technology started in 2005. OLED technology was created as a aternatif able to surpass the previous generation of the display screen, liquid crystal display (Liquid Crystal Display or LCD). OLED continue to be developed and applied tools in OLED technology tampilanTeknologi
OLED is an important tools in technology elektroluminensi. Technology has the basic concept of a light beam generated by the device due to the electric field is given. OLED technology was developed to obtain a broad view, flexible, inexpensive and can be used as an efficient screen for the display purposes.
Number of colors of light emanated by the OLED device from developing into a multi-color color. This phenomenon is obtained by making variations in electrical voltage that is given to the tools so that the OLED has the tools to become alternative tools such as flat screen display technology based on liquid crystals.
Mechanism of
Mechanism of OLED electrode that is if the electric field is given, the function of cathode akan turun and electron-electron moving from the cathode to the conduction band in the organic layer. These conditions lead to the emergence hole (hole) in the valence band. Anoda akan hole to encourage the move towards organic valence band. This process resulted in the occurrence of rekombinasi electron and hole in the organic layer where the electrons will come down and unite with holes ago to provide excess energy in the form of light photons with a certain wavelength. In the end will be one type of light beam with a wavelength depending on the type of material used light relay
