Video card definition function and types

Size[ edit ] Video cards for desktop computers come in one of two size profiles, which can allow a graphics card to be added even to small-sized PCs. Graphic Design Graphic design and video-editing software takes a good deal more memory than typical office software like word processors and spreadsheet programs, so a system with no video card running graphics-intensive programs would get bogged down and lag.

Water or air cooling are required for all video cards, with larger configurations needing water solutions to achieve proper performance.

Generally, the cards must be of the same model to be linked, and most low power cards are not able to be linked in this way. Dedicated vs integrated graphics[ edit ] Classical desktop computer architecture with a distinct graphics card over PCI Express. This can be fixed with a larger case that comes in sizes like mid tower and full tower.

The main advantages of integrated graphics include cost, compactness, simplicity and low energy consumption. Both approaches can be called integrated graphics. Power demands must be known before a proper supply is installed.

A dedicated graphics card has its own random access memory RAMits own cooling system, and dedicated power regulators, with all components designed specifically for processing video images. Some video cards are not of usual size, and are thus categorized as being low profile.

Zero-copy is not possible, data has to be copied, over the system memory bus, from one partition to the other.

Technology advances in gaming mean graphics are becoming more and more realistic; a high-quality video card makes the action smooth and the images brilliant.

Computers with multiple video cards may need power supplies in the — W range. Current high-performance video cards tend to consume a great deal of power. This piece of hardware provides additional memory and data allowances for image viewing on your computer system.

The GPU performs complex mathematical operations to determine how pixels of an image should appear on the monitor. This is done using either the PCIe bus on the motherboard, or, more commonly, a data bridge. Typical bandwidths for given memory technologies, missing are the memory latency.

What Are the Functions of a Video Card in a Computer?

Within the industry, video cards are sometimes called graphics add-in-boards, abbreviated as AIBs, [5] with the word "graphics" usually omitted.

Updating your video-card driver can often fix choppy or stuttering video, poor display performance or error codes in video programs.

What is the Function of a Graphics Card?

Cards from different chipset manufacturers, architectures cannot be used together for multi card scaling. Additionally, the operating system or an extra software package may provide certain programming APIs for applications to perform 3D rendering.

Heat extraction becomes a major design consideration for computers with two or more high-end video cards. Providing adequate cooling becomes a challenge in such computers.

Video cards require a well vented chassis and thermal solution. Updating the Driver Regardless of what graphics card you have installed, maintaining the latest drivers allows you to maximize its features and prevent errors.

Multi-card scaling[ edit ] Some graphics cards can be linked together to allow scaling of the graphics processing across multiple cards.A video card connects to the motherboard of a computer system and generates output images to display, and this quiz/worksheet combo will help you test your understanding of.

The video card is an expansion card that allows the computer to send graphical information to a video display device such as a monitor, TV, or projector. Some other names for a video card include graphics card, graphics adapter, display adapter, video adapter, video controller, and add-in boards (AIBs).

Video Card - is an expansion card whose function is to generate and output images to a display. Many video cards offer added functions, such as accelerated rendering of 3D scenes and 2D graphics, video capture, TV-tuner adapter, MPEG-2/MPEG-4 decoding, FireWire, light pen, TV output, or the ability to connect multiple monitors (multi-monitor).

The processing power of a graphics card or video card enables a computer to produce images in faster motion and better detail, a necessity for some computer games and video. A video card allows the monitor to produce fast action sequences, ideal for high definition video needs or the vivid colors and sharp lines of computerized flash apps and games.

The more frames per second -- a high definition video requires about 60 frames per second -- the smoother motion appears. A video card (also called a display card, graphics card, display adapter or graphics adapter) is an expansion card which generates a feed of output images to a display (such as a computer monitor).

Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics.
