Quick Summary

A datagram scheme is a method used in packet-switched networks for transmitting data. Instead of a dedicated connection, data is broken into small units called "packets" or "datagrams." Each datagram contains a header with addressing information and the actual data payload. These datagrams are sent independently across the network, potentially taking different routes to reach their destination. At the destination, the datagrams are reassembled in the correct order to reconstruct the original data file. This approach offers efficiency and fault tolerance, as packets can be rerouted if a path becomes unavailable. The Internet utilizes this datagram scheme.12
