Component Hardware – Understand about the definition or definition of hardware and its functions are accompanied by an example. The term hardware is often familiar to the computer, because the computer is composed of hardware and software. Maybe you are new to this term feel alien or less know what that means. Actually the term hardware can be said also as a hardware that is on a computer, to understand it more clearly let read the discussion on this paper.
A. Hardware Explanation
What is meant by Computer Hardware or Hardware is a device that has a physical, viewable, can be in touch, and has a specific function on a computer. Or hardware can be interpreted also as a device that has a physical form on the computer so it can be seen and touched. One of its functions is to support the computerization, such as receiving data input, data processing, and storing data, or release the results of data processing.
B. Types of Hardware
In general, hardware is divided into 3 (three) kinds, including as follows:
A. Input Device / Input Device
The input device is hardware whose function is to enter the data on the computer, the input data can be in the form of text, image, audio, and video. Examples of input devices such as mouse, keyboard, scanner, webcam, microphone, and so forth.
B. Process Device / Device Depot
The processing device is used to process or process data on the computer. This device can also be said as the brain of a computer, because it is an important tool to process the data entered. Examples of processing devices are CPU (Central Processing Unit), VGA, RAM, and so on.
C. Output Device / Output Device
The output device is a device whose function is to store and generate data and then issued through another device. For example data released in the form of text, images, audio or video. Examples of output devices such as monitors, projectors, printers, and so on.
But there are also dividing hardware into 5 (five) kinds, such as the above was the input device, process, and output coupled with storage devices and enhancements.
D. Storage / Storage Unit
Storage Unit is a component to store data or information on the computer. One example of a hard drive storage unit. Harddisk is a hardware that functions as a data storage unit on the computer, the hard drive is included into the secondary storage on the computer. Currently hard drive is not only installed on the inside of the computer, but there are also in pairs on the outside of the computer or more known as an external hard drive.
E. Peripherals / Additional Devices
Enhancements are a device whose function is to assist the computer in performing instructions or user commands. One example of a modem enhancement. Modem is a hardware device that functions as a communication tool that can convert digital signals into analog signals, or vice versa. Modems can connect a computer to the internet network.

C. Hardware Example On Computer
Below are some examples of hardware on the computer based on the type-type.
A. Example In Input Device
The keyboard is hardware that looks like a board and has a variety of buttons, whose function is to enter letters, lift, or symbols in want by computer users.
Mouse is a hardware that serves to move the cursor / pointer on the computer screen so it can make it easier to select the menus that exist on the computer, perform the process and edit the data.
Scanner is a hardware that serves to duplicate objects (such as pictures, notes etc.) into digital form.
There are still examples of input devices, such as joysticks for playing games, webcam, and so forth.
B. Example On Process Device
1. CPU / Processor
Processor is often referred to as the brain of a computer that can control various processes on a computer. Processor can run instructions, processing, calculation, or can run input and output commands.
VGA or Video Graphics Accelerator is hardware on a computer whose function is to process or process the graphics, then the results of the process will be displayed on the monitor.
RAM / Random Access Memory is hardware that functions for temporary data storage on computer. RAM will store and supply data needed by CPU / Processor to be processed into information.
There are still examples of device processing, such as power supply, LAN card, and so forth.
C. Example On Output Device
Monitor can be said as a hardware-shaped screen to display the results of processing data in various forms, for example in the form of text, images and video. Monitors also have a variety of sizes like television.
The projector is an optical device whose function is to display a processed image, on a flat field (projection screen, or other flat surface). The images can be images, videos, text and so on.
The printer serves to print data or information processing computer, generally data (text, images, graphics, etc.) are printed on paper media.
D. Example On Storage
Hard drive is a hardware that functions as a data storage unit or information on computers with large capacity. The hard drive is included into the secondary storage area on the computer. Currently hard drive not only in the computer only but there is also a hard disk that is potrable or known as an external hard drive.
Flashdisk is a tool of data storage on computer, Flashdisk has USB connector to connect it to computer or other media. Generally Flashdisk has a smaller storage capacity compared to the hard drive but as the development of Flashdisk storage technology-even greater. Generally Flashdisk is only used to move data from one computer to another.
3. Optical Disk
Is a data storage media that can be written / read by laser light. Optical Disk data storage media such as Compact Disk (CD) and Digital Versatile Disk (DVD).
E. Examples On Peripherals
Modem is a hardware device that functions as a communication tool that can convert digital signals into analog signals, or vice versa. With a modem then the computer can connect to the internet.
2. TV Tuner
TV Tuner is an enhancement that can enable a computer to receive television signals. So with TV Tuner computers can broadcast TV broadcasts from television stations.
