Graphics Card
A graphics card is a display adapter or video card that is placed in most computer machines to show high-clearness, color, definition, and overall look graphics data. It delivers a high-quality visual display, employing complex graphic methods, features, and functions to analyze and execute graphic data.
A graphics card is also known as a graphics adapter, graphics controller, graphics accelerator card, or graphics board.
The principal purpose of a graphics card is to relieve the processing responsibilities from the CPU or RAM. It features a specialized GPU and dedicated RAM to enable it swiftly handle graphical data. Like other CPUs, there is a separate heat sink in the card to keep heat out of the GPU. A card allows 3-D pictures, image rasterization, greater pixel ratio, a wider range of colors, and more to be shown. In addition, a card contains different extension connectors including AGP, HDMI, TV, and multiple monitors. You can incorporate a card in the motherboard or install it as an extension cord.

Usually, the graphics card is made in the form of a printed circuit board (expansion board) and inserted into an expansion slot, universal or specialized (AGP, PCI Express). Some have been made using dedicated enclosures, which are connected to the computer via a docking station or a cable. These are known as eGPUs.
Applications
The sophistication and processing power of modern GPUs means that cards are often the most complex and high-performance component in a computer, rivaling or exceeding the computer’s CPU (central processing unit).
High-end graphics cards do all the traditional tasks that they have always been responsible for, including rendering the ordinary graphics you use daily. They also render advanced 3D graphics in real-time for computer games.
Graphics professionals rely on high-end graphics cards as well. These days, photo, video, and graphics production applications rely on this, not the computer’s CPU, to perform advanced image processing, including computational photography, which uses artificial intelligence and computer processing to achieve results that previously could only have been done “in the lens” when photos or video were taken.
The GPUs are also sometimes used for their raw processing power to perform non-graphics work. Cryptocurrency miners, for example, rely on computers with high-end graphics cards to perform the sophisticated mining process for coins.
