Final answer:
A video card manages all images sent to a computer's display, rendering and displaying images, videos, and animations on the screen.
Step-by-step explanation:
The purpose of a video card is to manage all images sent to a computer's display. It is responsible for rendering and displaying images, videos, and animations on the screen. Without a video card, the computer would not be able to display any visual information.
A video card contains a GPU (Graphics Processing Unit) that handles the complex calculations needed to render graphics. It processes data from the computer CPU and converts it into signals that can be displayed on the monitor.
The video card connects to the motherboard of the computer and has its own dedicated memory called VRAM (Video Random Access Memory). This memory is used to store and access the data required for rendering images quickly and efficiently.
