Outline
Introduction
Virtual Communities Characteristic
Computer Mediated Communication
Asynchronous CMC
Synchronous CMC
Collaborative Mode
Conclusion
Introduction
Definition for “Places”
“The particular portion of space occupied by or
allocated to a person or thing.”
-
The American Heritage® Dictionary of the English
Language, Fourth Edition
Definition for “Virtual Communities”
“A group of people who may or may not meet
one another face-to-face, and who exchange
words and ideas through the mediation of
computer bulletin boards and networks.”
-
Rheingold, H. (1993).
Virtual Communities’
Characteristic
Shared interests
Shared values
Caring and nurturing discourse
A moral voice
Interactive information exchange that takes
into account previous communications
A common meeting place
More than two communicators
Does anyone know
what is CMC?
Computer-Mediated
Communication (CMC)
Human communication via computer
Emphasis on interaction between
humans using computer to connect
with one other
Focus on text based communication
CMC software has 3 categories:
Asynchronous
Synchronous
Collaborative
Asynchronous CMC
Communication which takes place at
different time or over a certain period of time.
Types of Asynchronous:
Email
List Server
Bulletin Board System
Computer Conferencing
Newsgroup
Voice Mail
Email
Allows users to send and receive
messages in an electronic Mailbox
Types of information-text, multimedia data
files
Advantages
24 hour accessibility from multiple locations
Cost effective
Fast and worldwide communication tool
Disadvantages
Junk mail
Risk of virus transmission
List Server
A list server is basically an E-mail list
where users can contact others who are on
the same E-mail list.
Example: ListServ (http://www.lsoft.com/)
Advantages
Can communicate with large numbers of
people with ease.
Communication between users with common
interest
Disadvantages
extensive list server activities can flood
mailboxes easily.
Bulletin Board System
moderated discussion board
Provide accessible electronic discussion
forum to anyone on the World Wide Web
(www).
Example: UTS Discussion Board
Advantages
Keep track of discussion
Allow sharing information/common interest
Disadvantages
Offline application is not available
Computer Conferencing
A form of electronic communication, where
people communicate with each other using
a computer network to transmit text
between them
Example: Microsoft Outlook
Advantages
Flexibility of meeting
Able to skip irrelevant discussion
Disadvantages
Need same software
Newsgroup
A discussion forum for particular subject
consists of written notes to a central
internet site and redistributed through
Usenet
Example: Usenet (found in DejaNews)
Advantages
Discussion content can remain focused
Governed by netiquette
Disadvantages
Usually not moderated
Normally is quite contentious
Voice Mail
An interactive computerized system for
answering and routing telephone calls, for
recording, saving and relaying messages.
Example: Optus Voice Mail Service
Advantages
voice recording allows longer messages
ability to leave detailed, private messages
Disadvantages
Might have difficulty in defining messages
Synchronous CMC
requires users to exchange
information at the same time, on the
same “channel” of communication.
Types of synchronous
Chatting system / Instant messages
Broadcast
Video conferencing
Chatting / Instant Messages
A synchronized communication
between people at the same
time and typing messages to
each other
Example: ICQ, IRC
Advantages
Real time conversation
Traceable conversation history
Disadvantages
Ambiguous identity
Difficulty with inexperience user
Broadcast
Transmission of radio /
television program for
public and general use.
Example: RealPlayer
Advantages
Usually free to customers
Up-to-date information
Disadvantages
Expensive set up &
maintenance fees
Video Conferencing
Discussion between groups of people at
different places being able to see and hear
each other
Pictures and sounds are carried by the
telecommunication network.
Examples: POTS, LAN.
Advantages
Able to deliver information rapidly
Increased access to global market
Disadvantages
Bandwidth limited
Incompatible information transmitted will corrupt
easily affecting viewing
Collaborative
Tools such as textual chats, white boards,
shared editors and video conferences
allow distributed team members to work
in groups, forming virtual teams.
Team members interact with each others
using different modes of communication –
asynchronous / synchronous, unicast,
broadcast or multicast.
Examples: TeamWave, LiveNet
Conclusion
The advances features of SCMC
and ACMC have allowed virtual
communications to become more
efficient and effective.
What do you think is the future of
CMC?
