WebThe Internet has its origin in the ARPANET network sponsored by the U.S. Department of Defense starting in the 1960s. The ARPANET was a datagram store-and-forward network that the Department of Defense liked for its ability to reroute packets around failures. This feature makes datagram networks survivable. WebFrame:Similar to a Packet, frames are small parts of a message in the network. a frame is the unit of data used in the OSI model’s data link layer. Datagram:The datagram represents a data unit of transfer in networking. Data transmitted in a network is divided into smaller parts called datagrams. Transport layer
