Asynchronous Communications • You can communicate without being connected at the same time as the person being contacted • Examples: E-mails and Conferencing. TU 170 Learning Online( Prepared By: M. Hussein Y. Mansour) Copyright 2005© ITC 19

Synchronous Communications • Both contacted parties must be present (online) at the same time of communication. • Examples: telephones and videoaudio conferencing. TU 170 Learning Online( Prepared By: M. Hussein Y. Mansour) Copyright 2005© ITC 20

Conferences and Face-to-Face meetings Advantages: • People can participate even if their circumstances would make face-to-face meetings difficult. • Some people who are housebound or have disabilities have found them especially liberating. • There is no problem in getting your turn to speak. • If you miss part of a discussion, there is a written record to let you catch up. TU 170 Learning Online( Prepared By: M. Hussein Y. Mansour) Copyright 2005© ITC 21

Conferences and Face-to-Face meetings Disadvantages: • • There is a delay between sending a message and receiving a reply, which may be minutes, hours, or even days, depending upon how often people read their messages. Asynchronous discussions are very much slower than synchronous ones. Messages are text-based, so tone of voice and body language are missing. You can only participate in a computer conference if you have a computer TU 170 Learning Online( Prepared By: M. Hussein Y. Mansour) Copyright 2005© ITC 22

Computer-Mediated-Communication (CMC) • Is any communication using computers, such as: – – Electronic Mail. Discussion Lists. Conferencing Software. World Wide Web (WWW). TU 170 Learning Online( Prepared By: M. Hussein Y. Mansour) Copyright 2005© ITC 23

Background on Networks Terminal–to–Mainframe system: • • All users were connected by using terminals. These terminals had a screen and a keyboard, but no computing power of their own. All the processing and data storage is done in the mainframe. Terminals do not do any processing. TU 170 Learning Online( Prepared By: M. Hussein Y. Mansour) Copyright 2005© ITC 24

Background on Networks (Cont. ) Client-Server System • • • Central machines called servers run continuously and are accessible to all authorized users whenever they want. Personal computers ‘clients’ connect to the servers at various times The processing load is split between clients and server. TU 170 Learning Online( Prepared By: M. Hussein Y.
