Render farm networks are a large collection of computers working together to render memory-heavy graphics. When someone makes an image or small animation, a single computer often can quickly render those graphics, but very large graphics may take hours, days or even weeks. This slows down the graphics workflow and can cause the computer to crash while rendering. To get around this problem and to make the rendering much faster, many computers are used simultaneously to render graphics. While there are other farm types, the render farm is only used for rendering.
