5. Importance of computer network

5.1. Allow source sharing

5.2. Put down barriers between information held on by several system

5.3. Allow user to access remote programs and remote database

5.4. Faster communication possibilities

6. Multimedia content

6.1. Basic types

6.1.1. text For information storage,retrieval, and presentation

6.1.2. still images Time-invariant graphic images: photographs and drawings Take more space than text, must consider for network tranmission.

6.1.3. moving images Video and animation, time-varying images. Consume space too

6.1.4. sound Human voice,digital-voice,music Enhance the effect of multimedia system.

6.2. Structure

6.2.1. In a networked multimedia system the component of a single multimedia presentation may be placed on different sites.

6.3. Type

6.3.1. Extended types interactive links Hypermedia system allows users to navigate through the information in a nonlinear manner virtual reality Needs dedicated hardware Create a very close interaction between the user's senses & the computer system.

7. Multimedia Network (MMNET)

7.1. Allows storage, access and transmission of multimedia information.

7.2. A composite filed

11. Network Standards

11.1. Definition

11.1.1. Rules of operation that govern communication between two(or more) hardware or software processes on different machine.

11.2. Advantage

11.2.1. allow hardware and software processes from different vendors to interoperate( i.e. work together) essential for two or more equipment that used for application interpret and integrated information stream in the same way ensure both communicating parties utilize the same standards for detecting information stream

11.2.2. Needs timely and errorless transmisson

11.2.3. open standards allow more competition, increase speed of development and might lowering the price for network hardware and software

12. Popular network standards organization

12.1. ISO

12.2. IETF
