What is a sprite sheet and its purpose in animation?

A sprite sheet is a single image file that contains multiple frames or images of a character or object for animation purposes. The primary function of a sprite sheet is to optimize performance in animations and games by reducing the number of individual image files that need to be loaded. When using a sprite sheet, the animation frames can be displayed in quick succession to create the illusion of movement. This efficiency is vital for enhancing performance, especially in environments where loading times or memory usage need to be minimized.

Other choices do not correctly define a sprite sheet. Audio files pertain to sound effects and do not involve visual components like a sprite sheet. A sequence of images for background design does not fit the definition of a sprite sheet, which focuses on character or object animation. Lastly, a template for user interface design also does not relate to sprite sheets, as it pertains to the arrangement of visual elements on a display, rather than the management of animated graphics.
