Synchronous communication is direct communication where the
communicators are time synchronized. This means that all
parties involved in the communication are present at the
same time. This includes, but is not limited to, a telephone
conversation (not texting), a company board meeting, a chat
room event and instant messaging. Asynchronous communication
does not require that all parties involved in the
communication to be present at the same time. Some examples
are e-mail messages, discussion boards, blogging, and text
messaging over cell phones. In distance (specifically
online) education asynchronous communication is the major
(sometimes the only) method of communication. Usually, we
use different discussion boards in each class with each
having its own purpose.
A start bit and a stop bit are added to each data segment
for asynchronous communications. For synchronous
communication, both the start bit and stop bit ane
eliminated, so a faster transmission speed is achieved.
With INS-Net, the standard transmission speed of
asynchronous communication is 38.4 kbps, while that of
synchronous communication is 64 kbps or 128 kbps.
