VGA card is part of a computer, inside the CPU that is important to show the process output to the monitor. Without VGA card, the computer screen will not display anything blank. VGA card itself is a form of extra slot or motherboard manufacturer congenital or collectively, VGA on board. What kind of VGA card are? Please observe the image below.
Among other parts of memory and a cooling fan. Same function, which displays text and images to the monitor, just different colors and designs, depending on the manufacturing side. The fan needed to cool the hot components of the VGA card, because this part is working quite hard all the time.
VGA card shown above is an additional VGA, not on board (not integrated with the motherboard). The advantage of non VGA card on board is that we can easily replace them with new ones in case of damage to or want to improve the performance of our computer graphics.
2. CASING
Casing is the computer that serves as protective clothing or from the CPU. A common form is a square box, but can be modified for those who enjoy tinkering with this case.In addition to the CPU protector, casing can also serve as an additional cooling. Because usually, when modern casing is equipped with a cooling fan that his number could be more than one fruit.
Another main function is as a foundation to put the various parts of other computers, especially the CPU, such as motherboard, VGA card, sound card and others.
As a patron, useful to protect the inside casing of dirt or dust, from a collision with another object, so that the vital parts that will be safe and not easily damaged.
In addition to these primary functions, the casing can also be performed with a variety of colors and shapes to suit our desires. Of course, this modified casing is more expensive.
Most important in the selection of casing is its main function. Computer so that we are in a safe and secure.
3. POWER SUPPLY
Still inside the computer, stored in the CPU power supply. True to its name this power supply work supply power to every part of the computer to run. Commonly used in the home PC is a ATX type. For more details, see the image below.
Of course, the electricity flows is minimal or minimized. While the power supply itself is still a large electrical voltage, so it is strictly forbidden to touch it.
4. PROCESSOR
This paper discusses the continuation of the previous contents of the CPU. Yesterday was discussed on the motherboard, this time we will discuss the processor. What processor does it? How can it be? Function for what? Below it will try to explain what processor. Processor is a very important part of the computer. He can be likened to a computer brain. That is an electronic circuit that functions to logically respond to and process all the instructions that turn on the computer.
How does it look like? Take a look at the picture below.
That is the latest image processor, both Intel and AMD.
5. MOTHERBOARD
This paper is for those who want to know the contents of the CPU, such as motherboard or mainboard. Is the parent or within the main CPU. Serves as the circuit boards of various other supporting components.
Like what form the motherboard? Below is a sample image motherboard "Gigabyte GA-MA69GM-S2H".
You see the colorful it?
It is a place holder for attaching cards are required, such as the VGA card, memory card, TV Tuner, Video card, and others.
6. KEYBOARD, MOUSE AND MONITOR
Well, this input section consisting of keyboard and mouse. In the 1990s, only a keyboard input device only. Subsequent development of emerging mouse, pen (a pen-shaped). Now there is a finger touch input device (touch screen) and sound (Kalima command). Which is generally used for home computers is the keyboard and mouse. Its function is of course to enter data.
Finally, the monitor, output while, because it just seemed for a while just on the screen. Its function is to look at the input or the current program.
