What is the method of slicing digital messages into parcels transmitting them along different communication paths and reassembling them at their destination called?

The method of slicing digital messages into parcels, transmitting them along different communication paths, and reassembling them at their destination is called "packet switching." This technique breaks down data into smaller packets, which can take various routes through a network, optimizing bandwidth and improving efficiency. Once all packets arrive at their destination, they are reassembled in the correct order to form the original message. Packet switching is a fundamental principle behind most modern data networks, including the internet.
