GM111 Introduction to Multimedia Lecture 01 Quiz

Multimedia Basics

• Multimedia is a combination of text, graphic, sound, animation, and video delivered interactively to the user by electronic or digitally manipulated means.
• The main purpose of multimedia is to provide an interactive experience to the user.

Multimedia Elements

• The element of multimedia described as a two-dimensional figure or illustration is a graphic.
• In multimedia, 'text' refers to a sequence of characters that convey information.
• The main purpose of graphics in multimedia is to provide visual representation and enhance the user experience.

Graphics in Multimedia

• Raster (bitmap) graphics are resolution dependent and have a main advantage of being able to display detailed and complex images.
• Software useful for creating bitmap images includes Adobe Photoshop.
• Vector graphics are resolution independent and have a characteristic of being scalable without losing quality.
• A common disadvantage of vector graphics is that they may not be suitable for displaying complex images.
• The primary difference between pictures and images in the context of multimedia is that pictures are usually raster graphics, while images can be either raster or vector graphics.
• Raster graphics represent an image as a rectangular grid of colored squares.
• The distinguishing feature of drawing programs in the context of multimedia graphics is that they use vectors to create images.
• In multimedia applications, the main purpose of graphical images is to provide visual representation and enhance the user experience.
• The key difference between draw-type graphics and raster (bitmap) graphics in multimedia is that draw-type graphics use vectors to create images, while raster graphics use a grid of pixels.

Interactive Multimedia

• In interactive multimedia, users have control over the content being displayed.
• Authoring tools, such as Adobe Flash, are designed to merge multimedia elements into a project and provide user interaction.

Video and Animation

• Technology that captures, records, processes, transmits, and reconstructs moving pictures is video technology.
• The illusion of motion created by the consecutive display of images is a characteristic of animation.
