Pengertian VGA Card Komputer Dan Jenisnya

Definition VGA card computer and type
VGA card or the like is also called VGA card, abbreviated from "Video Graphics Accelerator" the functioning of the process data graphics to be displayed on a computer screen. VGA prossesor also has what is called the GPU "Graphics Processing Unit" and also requires memory. VGA card serves to translate the computer output to the monitor. For the graphic design process or playing a video game, etc., required high-powered graphics card.
Function Card VGA (Video Graphics Accelerator) is to translate or convert the digital signals from the computer into graphical display on the monitor screen. VGA card also has a function to translate the computer output to the monitor. To play video games, create graphic design and so on.
Types VGA On Computer include:
   1. ISA VGA card is a type of card VGA (Video Graphics Accelerator), which is inserted in the expansion slots ISA (Industry Standard Architecture) bus is still bersistemkan I / O 8-bit or 16-bit.

   2. EISA VGA card is the type of card Video Graphics Accelerator, which can be attached to the expansion slot EISA (Extended Industry Standard Architecture) bus is a 32-bit I / O system.

   3. PCI VGA card is the type of card VGA (Video Graphics Accelerator) mounted on a PCI expansion slot (Peripheral Component Interconnect) bus is 32-bit or 64-bit I / O system.

   4. VGA card is AGP VGA card types that can be attached to the expansion slot AGP (Accelerated Graphics Port) bus is 128-bit and 256-bit I / O system.

  5.  VGA card PCI Express (PCIe) is a type of VGA card that can be inserted in the expansion slot PCIe (Peripheral Component Interconnect Express) bus which is berangkaian series I / O system with its transfer speed reaches up to 32 GByte / s.

VGA card shape, covering:
VGA cards are divided into two (2) types according to their form, ie VGA card on board and add-on VGA card. VGA card on board can you find in all the motherboard / mainboard when you buy a computer or laptop because they were a package deal. This VGA can you use to display the output on the screen very well. Actually, if you do not do high-level graphics processing, we do not require add-on VGA card. If you feel the on-board VGA card is less than the maximum or less sophisticated, you can add the add-on VGA card. It is primarily for you graphic designers, 3D game player, movie editor, etc.
Therefore, the presence of the add-on VGA card is according to your needs. When it is apparent that the VGA on board you will not be able to do what you need, then the add-on VGA card can be added. But this only applies to the PC (Personal Computer) just cause to other devices such as laptops are not available card slot for additional add-on VGA card. Moreover, the add-on VGA card also makes the need for electrical power on the computer to be high and this can only be met by a PC only
Weaknesses and strengths of each of the VGA card
On-board VGA card has the advantage of already bundled with mainboard / motherboard, so it certainly will not be any problems with your computer when it is used. Moreover, the on-board VGA card can be said to be free. Every time you buy a motherboard, VGA card must have been installed on-board. Of course, this is very good for you that have budget / funds are limited in buying a computer. While shortcomings of on-board VGA card is not having its own memory. This resulted in "cutting" the memory of the main CPU or your laptop, known as RAM (Random Access Memory) for use by VGA. If RAM is limited, of course, overall PC performance will be slowed down.
As for the add-on VGA card that excess is able to do the job of rendering heavy and also not "eat" the main memory or RAM in the CPU (Central Processing Unit). A process that involves the graphics will not overwhelm computer processors and you will be faster in the process something. The disadvantage is the price is a bit expensive, even more expensive than a set motherboard / mainboard coupled with the processor and RAM. In addition, other drawbacks that make your computer requires electrical power somewhat larger than usual. If you have a power supply capacity is not great, then the performance of the PC / computer will not normal, so that you are required to replace the power supply with a somewhat higher and this certainly do not come cheap or expensive.
