Lesson 5

Interactivity

A computer-delivered electronic system that allows us to navigate, integrate, and manipulate different types of media such as text, sounds, video, computer graphics, and animations. And also, we could directly send and receive messages in several ways, and with that, we could accomplish easily and engage what we’re looking for.

Multimedia

It refers to any data of a computer that can be shown using music, video, or animation in conjunction with traditional media. This data can be processed digitally, represented, stored, and transmitted.
