Introduction to Multimedia
Multimedia is the use of more than one medium of expression or communication to present information or content. It typically combines text, audio, images, animation, video, and interactive elements to enhance the way information is conveyed and understood. Unlike traditional printed or static materials, multimedia enables richer, more engaging experiences by allowing dynamic and often user-driven interaction.
