Switching compared with multiplexing
Short answer
Switching forwards data from input to correct output port to reach the destination, used inside network nodes. Multiplexing combines many signals onto one shared link, used at ends. Switching types: circuit, packet, message; multiplexing types: FDM, TDM, WDM.
What do you mean by switching in communication? Compare switching with multiplexing.
Switching
Switching is the process of forwarding data from an input port of a network node to a suitable output port so that it reaches the destination across a network. It makes connections between any two nodes without a direct link between every pair. Types are circuit, packet and message switching.
Comparison with multiplexing
| Point | Switching | Multiplexing |
|---|---|---|
| Purpose | Select a path between source and destination | Combine many signals onto one link |
| Used at | Inside the network (nodes/exchange) | At the ends of a link |
| Function | Routes data to the correct output | MUX combines, DEMUX separates |
| Link usage | Connects many links | Shares one link |
| Types | Circuit, packet, message | FDM, TDM, WDM |
| Aim | Reachability to the right destination | Efficient use of bandwidth |
| Devices | Switch, router | Multiplexer, demultiplexer |
