Definition and Function of VGA Card, VGA Card -Pengertian by fungi VGA (Video Graphics Adapter) as we know it is changing into a digital signal on a computer monitor screen graphic display.
VGA is an analog computer display standard first marketed by IBM in 1987 Although the standard VGA is no longer used because it has been replaced by a newer standard, VGA is implemented on Pocket PCs. VGA was the last graphical standard that is followed by the majority of computer graphics card manufacturer. Display Windows is still using the VGA mode is supported by many manufacturers of monitors and graphics cards.
The term VGA is often used to refer to a resolution of 640 × 480 screen size, any graphics card hardware makers. VGA card is useful to translate the computer output to the monitor. For the graphic design process or play video games, needed a high-powered graphics card. Renowned manufacturer of graphics cards include ATI and nVidia.
In addition, the VGA can also refer to the 15-pin VGA connector is still widely used to deliver analog video signal to the monitor. Standard VGA was officially superseded by IBM's XGA standard, but in fact it was replaced by the Super VGA VGA.
VGA Card function is to change the digital signal from a computer display graphics on the screen. Card VGA (Video Graphics Adapter) allows to translate the output (output) to the computer monitor. For drawing / graphic design or to play games. VGA card is often also called the Card display, VGA card or graphics card.
Place attachment called a graphics card expansion slots. Chipset / processor on the VGA card, many kinds because each plant has its flagship chipset VGA card. There are many manufacturers like NVidia Chipset VGA card, 3DFX, S3, ATI, Matrox, SiS, Cirrus Logic, Number Nine (# 9), Trident, Tseng, 3D Labs, STB, OTI, and so on.
VGA card using several kinds of memory such as:
DRAM (Dynamic RAM) speed 80 ns or 70 ns, there is also the MD-RAM (Multiple Dynamic RAM) which uses DRAM layered. DRAM is used in many graphics cards 8, 16, or 32 bits. The use of DRAM is intended for entry level computer, which does not require high speed and multiple colors.
EDO RAM speed 60 ns to 35 ns, EDO RAM can be easily found on the 64-bit graphics card. EDO RAM is commonly used has a speed of 60 MHz 60 / 40ns. Examples of VGA cards that use EDO memory is WinFast S280 / S600 3D, Diamond Stealth 3D 2000, ATI Mach 64, and so on.
VRAM (Video RAM) 20 or 10 ns speed, VRAM is more expensive than DRAM because VRAM is faster than DRAM. VRAM usage on VGA card is intended for upper-class computers. Usually mounted on a VGA VRAM concentrated for graphic design. Examples of the use of VRAM VGA card is Diamond Fire GL, Diamond Stealth 3D 3000, Diamond Stealth 64, and so forth.
SGRAM (Synchronous Graphics RAM) speed of less than 10 ns, SGRAM on VGA card is also based on technology SDRAM main memory of the computer. SGRAM is widely used in high-class graphics card that has the capability of 3D accelerator. Examples of the use SGRAM VGA card is a Matrox MGA Millennium, Matrox Mystique 3D, Diamond Stealth II S220, Diamond Viper, ASUS 3D Explorer, ATI 3D Rage II Pro, and so forth.
Rambus Rambus on the VGA card using a computer is still a little (RAMBUS memory is used in gaming machines Nintendo, Sega, so far only the production of graphics card Creative Labs (MA-302, MA-332 3D Graphic and Graphic Blaster Blaster xXtreme) who use .
Graphic Accelerator chipsets today already incorporate a built-in 3D acceleration capability on the VGA card. In addition to the VGA card, there is now a supporter of the so-called computer pheriperal 3D accelerator. 3D accelerator function to process / translate the data / more perfect 3D image. 3D accelerator whose existence does not require IRQ longer able to perform manipulations of complex 3D graphics. For example in 3D games may appear far more realistic image. For many 3D graphics processing functions formerly performed by the processor on the motherboard, now done by the 3D graphics processor on the 3D accelerator. With this division of labor, the processor can do a lot more work that other processing. In addition, the programmer does not need to create 3D graphics functions, because these functions have been provided by the 3D accelerator. 3D chipset on the VGA card is not as good when using 3D accelerator as supporters (3D accelerator installed separately along with VGA card). Nonetheless 3D Chipset VGA card supports 'some' facilities 3D acceleration 3D accelerator. As an important note that, 3D accelerator function is optimal if the software / games that run utilizing special functions on the 3D accelerator. Software / games that support this feature begins to develop, which is already known is support for 3D accelerator that has a 3D VooDoo FX chipset, Rendition Verite, and Permedia 3D Labs.
PCI VGA, VGA Card can be used by installing the vga slot, vga this type has been rarely used, due to the limited features, its features are part of the slot on the front there is coakan, and the type of the pin vertically straight, more details, see the following picture:

AGP VGA, VGA AGP early type made vga agp, due to the significant increase in data transfer from the memory, cpu to display equipment, so it made for installing agp slot Kenis agp vga, vga agp launched based on the value of the voltage is used, the AGP 1x and 2x with voltage 3.3 v, while the 4x and 8x 1.5 volts. vga agp last appears to be in the pro and pro universal with capability 3.3 and 1.5 volts. The characteristics of this vga is a form of its vertical pin with honeycomb-like shape formation, here is a picture vga agp and agp slots it:

VGA PCI Express, the development of the next pci slot has a remarkable ability, with the name of PCI Express, is designed to install the latest equipment, 2 PCI Express version of the famous is PCI Express 1 x and 16 x, 16 x PCI Express is used exclusively for installing vga type of PCI Express, and 1x for the purposes of installing additional equipment. Physical characteristics pci express vga type is to look at the shape that has a reverse form of regular PCI.

That is the definition and Fungi VGA card that I summarized from several sources. Hopefully what I pour in this blog can be useful.
