It can be linear, with a set progression, or non-linear, allowing user control over navigation. Common multimedia elements include text, photographs, sound, video clips, and animations. Multimedia has various uses in fields like business and education, providing opportunities for creative and engaging learning experiences. While costly and time-consuming to create, multimedia can effectively convey concepts through multiple media forms.
