Hardware (Hardware)

Computer system components:- Hardware: physical devices used to perform computing.- Software: computer programs used to perform computing operations.
# Hardware (Hardware) is a device that serves to input process (input), data processing and output (output).Input device (Input Devices) Input device functions to enter data or input to processed into information or output .Consist of: mouse, keyboard.
# The Central Processing Unit (CENTRAL PROCESSING UNIT (CPU))In the process of working a computer, the processor is the most important partthe input process and output.Output device (Output Devices) One device that serves to see the results of the process input, as for the device are as follows:- Monitor- mMonitor is one useful tool isplays information generated from the input process- Printer (print device)
# This device functions to print the results of the process input (Input), the form of text or image- Speaker This device serves to produce a sound that has been processed on the computer.- Data Storage Media (Storage Devices) Media storage function for storing data or information which in the computer. Data storage media comprises various types of Other:- Hard Driver (Disk) Is an internal storage of large capacity, currently reaching capacity of 120 GB hard drive. The price of this medium quite expensive.- Memory an electronic data storage media. Memory directly associated with the microprocessor.- Motherboards is the main circuit board in which all internal components are connected to each other. Components / other systems are also often directly integrated in it or connected with the interface.- Power Supply resources to distribute the entire sub-computer system. 
# Operating Systembasic software that allows users to interact with computers. Without an operating system, user's impossible to "use" the computer.- IDE (Integrated Device Electronics) Controller an interface for controlling hard drives, CD-ROM drive, and floppy disk drives.- PCI bus (Peripheral Component Interconnect) slot on the motherboard that are used to connect additional components to the computer. The bus is a data point in the motherboard.- SCSI (Small / Simple Computer System Interface) interface for adding external devices such as scanners, hard drives, CDROM drives, etc.. into the computer. Not all external devices SCSI facilities.- Graphics Card (Graphics Card) cards that work translates image data from the computer to a specific format that can be displayed on the screen.- AGP (Accelerated Graphics Port) very high-speed interface is used to connect to the computer graphics card. Serves to improve the quality of graphic impressions, for example, to show 3D.- Sound card (Sound Card): cards that function to record or play an audio recording, and rang the audio information. This card works on the basis of the conversion of digital data to analog or vice versa (D / A or A / D converter).
