Linear communication is a one-way process conducted in a straight line (linear way) toward the main point. Here, the sender is more important, encoding and transmitting the message through a channel in the presence of noise; and the receiver only decoding the information without giving feedback or response. Non-linear communication is one that is not in a straight line. It is interactive. Circular communication is conducted in a circular manner around the main point. The point may be left unstated because the verbal and nonverbal information provided is sufficient for understanding. Mechanised communication is one that typically includes written or electronic communications and can be used as an archive for messages.
