Do computer networks and traditional telephone networks exchange data in the same way?

The way data is exchanged on the telephone network is called circuit switching in technical terms. And the computer network data exchange method is called message switching or packet switching. The different characteristics are:

Circuit switching, the need to establish a connection, is end-to-end transmission, suitable for large-scale data exchange, need a good channel.

The message switching method, which does not require the establishment of a connection, is a point-to-point transmission mode, which is transmitted through routers in each network, and can improve channel utilization
