What role do video cards play in a computer?

Answer 1

A video card's purpose is to support the use of graphics on a computer. It has two primary purposes, to output video signals to a supported device, such as a monitor or television, and to facilitate routines integral to placing visual data onto the attached device. Classic video cards provide only a "frame buffer", which is an area of system memory that is mapped to the video card's memory buffers; writing an image to this buffer will cause that image to appear on the monitor. Modern video cards also provide 3D rendering and memory for holding 3D objects such as textures. These cards are optimized for displaying 3D images in realtime without tying up the CPU for those operations.

Answer 2

Video cards, sometimes known as graphic cards, are helpful in storing memory and plays other storage roles in a computer. Video cards help to store the memory of a specific game and replay it on a different computer.

Answer 3

A video card is used to calculate the renderings of your computer's display. From your monitor's resolution to complex game physics and textures. All computers have a Graphics processing unit (GPU). However, cheaper computers have integrated GPU's which means they are part of the CPU and don't run high resolutions and high-end games that well. The dedicated GPU's such as the Nvidia Gtx series, are able to run complex games, auto cad programs, and video editing programs. Dedicated graphics cards still have integrated, programs that use small amounts of GPU power are run on the integrated GPU's to save battery(for laptops), or save energy and heating-up in general. But when you run a high end game or program, Your pc will automatically switch to the dedicated GPU. Hope this info helped!
