A graphic, or graphical image, is a digital representation of nontext information such as drawing, chat, or photo. Many Web pages use animation, which is the appearance of motion created by displaying a series of still images in sequence. On the Web, you can listen to audio clips and live audio. Audio includes music, speech or any other sound. On the Web, you can view video clips or watch live video. Video consists of full-motion images that are played back at various speeds.
