Section1: Joining the online world:

1.1 Introduction:

- Day by day the Internet and its’ applications become more and more important. - In the past, if some body wants to send a message to some body else, it took days or months to receive. But now by using e-mail through the Internet, It takes just seconds to receive. Therefore joining the online world is a crucial part of our daily life. - Section 1.2 will present e-mail and conferences and the differences between them. - In section 1.3 we want to discuss Computer Mediate Communication (CMC) and the Arab OU first class system.

1.2 E-Mail and Conferencing:

- When the people used the shared computer for the scientific calculations and data manipulation, people discovered that they can send messages through this network, then the shared computer took this message and sent it to another person, thus the idea of e-mail was born. - After the Internet had been discovered in 1969, the e-mail was used by the academic and scientific people, But now all the internet users can use it. - Synchronous v.s. Asynchronous communication:

• Synchronous communication:
- Both contacted parties must be present at the same time of communication. Communication between sender and receiver is rather fast - Examples: telephone calls and video\audio conferencing. • Asynchronous communication:

- This means that one could communicate without being connected at the same time as the person being contacted There could be a communication delay, which might range from minutes to week and is therefore a slower communication.
