| Graphics Card or display card is used for high resolution display purpose in computer system. Although these day on-board display port is available on the motherboards of PC, but in some cases where the high graphics resolution is required then add-on graphics card is required.
In past years, the Graphics Card was always required because the motherboard did not have its own graphics/ display port. It required connecting the separate display card on the ISA, PCI or AGP slots provided on the motherboard. But these days the motherboard is having its own graphics port i.e. the graphics chip is embedded on the board itself. One need to buy the graphics card only in case high resolution is required for gaming purpose or for certain other graphics applications.
Types of Graphics Card
The main types of Graphics Cards are MGA/CGA, VGA, SVGA, PCI-VGA and AGP / PCI-e depending upon their technical architecture. Therese days AGP / PCI-e cards are being used; all other types of graphics cards have gone obsolete. MGA/ CGA (mono and color graphic adapter) were used in very old days before 1990s; there only purpose was to show the display on the monitor in terms of alphabets/ letters, there was nothing called a video stream kind of thing on those monitors. Then came VGA (versatile graphic adapter) which were able to provide display on VGA monitors with little high resolution and were succeeded by SVGA (Super VGA) and PCI-VGA cards. VGA-VGA cards were able to provide high resolution graphics for games and graphics designing software applications. The high video RAM was also supported in PCI-VGA cards say up to 4 MB. But still in some3-D games, video streaming and high resolution graphic applications more video memory was required to run them properly which was handled by AGP (Accelerated Graphics Port) and PCI-express Adapters which support the video memory in GBs.
