Unit III: Multiplexing and Switching | BCA 6th Semester Data Communication and Computer Network Notes Pdf

Multiplexing is the set of techniques that allows the simultaneous transmission of multiple signals across a single data link. For example, one cable can carry a hundred channels of TV.

Switching is a technique which is used in a large network; it means those networks that contain a large number of node, wire, device etc. In larger networks, it is difficult to connect nodes point to point. So in this situation, we use Switching Technique.

In this “Multiplexing and Switching - Data Communication and Computer Network” you will learn about following topics:

1. Multiplexing
2. Frequency Division Multiplexing (FDM)
3. Time Division Multiplexing (TDM)
4. Types of Time Division Multiplexing
