7. Computer system can be connected to other machines and electronic devices.
8. Naturally people get attraction toward computer learning.
9. Usage of computer products increases in business environments.

Disadvantages

1. Overall cost of computer system increases.
2. Computer user must be well trained to take full advantage of multimedia applications.
3. Sometimes overall performance of computer slows down.
