Advantages of Multiplexing
- Multiplexing allows the efficient usage of computer resources.
- Multiplexing is Cost effective
- Frequency Divison Multiplexing allows simultaneous transmission of multiple signals
- Time Division Multiplexing is used for Fair Resource Allocation that is each device is allocated a specific time band for their transmission.
- Code Division Multiplexing is used to increase the security so that only authorized user can access data.
- Multiplexing also provide scalability.
Multiplexing (Channel Sharing) in Computer Network
Multiplexing means multiple sources but one link. An alternative approach is a Direct point-to-point connection, but it has several problems as it requires an I/O port for each device, a need line for each device, and also a large amount of wiring needed if on different floors. Instead, if we use a multiplexer approach then all devices are connected to MUX and one line to the host, the link carries multiple channels of information and several lines equal to the number of lines out.
