Analogy

Imagine a multimedia experience as a delicious pizza. The pizza consists of different ingredients, such as the crust, sauce, cheese, and various toppings. Similarly, multimedia consists of different media components, such as text, graphics, audio, video, and animation. Just as each ingredient contributes to the overall taste and experience of the pizza, each media component enhances the overall user experience in multimedia. The multimedia system architecture can be compared to the kitchen where the pizza is prepared. The input devices are like the utensils used to prepare the ingredients, the processing units are like the chef who assembles the pizza, the storage devices are like the pantry where the ingredients are stored, the output devices are like the serving plates, and the communication networks are like the waiters who deliver the pizza to the customers. The evolving technologies for multimedia are like new flavors and toppings that keep the pizza experience exciting and innovative. Defining objects for multimedia systems is like creating a recipe for the pizza, specifying the ingredients and their attributes.
