A graphics card processes image data to display images and videos on a computer. It allows the computer to display complex images such as streaming videos and 3d animations. It also determines display attributes such as resolution, clarity, and sharpness. It comes in a printed circuit board installed in an expansion slot or an Accelerated Graphics Port (AGP).
Types of Graphics Cards
Kinds of Graphics Cards include the following:
A VGA card determines the number of colors and amount of pixels on the screen. It depends on the computer's video memory (VRAM) to enhance image color and size. It has a digital-to-analog converter (DAC) and its own memory. It normally uses the computer’s processor to process data and execute video operations.
Video capture card
A video capture card converts television signals to a computer RGB format and vice versa. It imports analog videos from TVs, VCRs, and analog camcorders to the computer for editing or movie making. It affects the display size, format, and motion speed of images and videos.
3D graphic accelerator card
A 3D graphic accelerator card is a special hardware card that enhances the speed of three-dimensional movements. It is plugged into the motherboard's PCI or AGP slot. It is available in low, medium, and high graphic acceleration. It is commonly used in computers designed for 3D gaming.
Choosing Graphics Cards (Buying tips)
Card memory: Choose a graphics card with the greatest memory capacity you can afford for better performance, greater speed, and smoother transition.
