Second Chapter Lesson-3: Data transmission mode.

At the end of this lesson-1. You will be able to explain the concept of data transmission mode. 2. You will be able to classify the data transmission mode. The direction of transmitting data from source to one or more destination is called data transmission mode. or The way in which data is transmitted from one device to another device is known as transmission mode. The transmission mode is also known as the communication mode. Each communication channel has a direction associated with it, and transmission media provide the direction. Therefore, the transmission mode is a...
