CMC allows for synchronous
and asynchronous communication.
Synchronous communication
means that communication is taking place in real time. Live chatting is an
example. It can be in voice, audio or text mode or a combination of two or all
of them.
Asynchronous communication
means that users can read/speak/watch and write/hear/record messages stored on
a server, at a later point.
Depending on the time
of access, synchronous media can be used as asynchronous media, and vice versa.
For example, somebody sends a chat message, which is accessed the next day becomes asynchronous, but using synchronous medium. Similarly, two people can respond to emails
instantly like in live chat, to make it a synchronous medium.
Mode: one to
one, one to many, many to one and many to many mode.
Participants could be
familiar or unfamiliar people.
Topics could be anything
from anywhere. Information, news, media, video, etc. could become your topic.
Written mode of
communication lets learners take time in composing their responses, giving
ample time to reflect on language before and after production.
Listserv type of
applications can distribute messages to all simultaneously making communication
easier.
Web publishing is
another means used by teachers to make use of the writing skills of learners.
