What is multimedia and Use of multimedia in education and entertainment?


Multimedia is an advanced technology that facilitates integration of text, data, image, graphics, audio, video animation in digital form. It provides new ways to enhance the delivery of information and its impact on the user. Multimedia is information displayed in picture/sound form and it does not include plain text exclusively. Thus it includes pictures, audio and video which are captured and digitized by input devices to get the information ready for manipulation by the computer.

In other word we can say that Multimedia is a combination of text, graphics, audio and video. It is a new trend in one computer science because it combines different media in one computer application, it is called multimedia. This enables the computer to be used as an entertainment and educational tool besides just a business tool.

2. Images

1. Line Drawing Graphics: Line drawing graphics lie in the form of 2D and 3D pictures using mathematical representation of simple objects like lines, circles, arcs etc. The area of computer graphics that deals with this type of picture is known as generative graphics.

2. Images Graphics: In this graphics photographs composed of a collection of pixels, which are arranged in 2 D matrix. The area of computer graphics that deals with this type of pictures is called cognitive graphics.

· Students in engineering colleges use interactive multimedia presentations to learn the basics of electronic, implement test and manipulate the circuit they design on a computer.

· Training/classroom multimedia, appropriately known as CBT (Computer Based Training/Tutorials) uses multimedia technology to teach academic curriculum.

Use of multimedia in Entertainment:

· Entertainment and media industry are benefitted by multimedia technology. Images, animation and sound are broadly used for creation animation movies.

· A computer is broadly used by musicians to record, edit and mix sounds.

· It is used to entertainment CDs, games, comics and stories for children.

· Video and entertainment films are formed using computers and stored on CD-ROM. Music can also be stored on CDs and played using multimedia software package such as media player etc.

· Some of the techniques commonly used for creating video films for different purposes like video editing, mixing and 3D animation.
