what is vedio card??
A video card
is rectangular in shape with numerous contacts on the bottom of the card and one or more ports on the side for connection to video displays and other devices.
The video card installs in an expansion slot on the motherboard. While some video cards and most other cards in a computer are of the PCI format, video cards come in other formats as well including AGP and PCIe. These additional formats provide a more efficient way for the video card to communicate with the CPU and other components.
Since the motherboard, case, and expansion cards are designed with compatibility in mind, the side of the video card fits just outside the back of the case when installed, making its ports available for use. Some video cards have only one port for connection to a standard monitor or projector while more advanced cards may have ports for connections to multiple output sources including additional monitors and televisions. Still other cards may have inputs for video editing and other advanced tasks.
