What is the primary function of a datagram in a packet-switched network?

The primary function of a datagram in a packet-switched network is to provide a structured format for data transfer. Datagram is a fundamental unit of data used in this type of networking, where data is divided into smaller packets for efficient routing. Each datagram contains the necessary information, such as source and destination addresses, in a format that allows for seamless transmission over the network. This structured approach enables the network to handle various types of data and routing paths, allowing for dynamic and flexible communication.

In contrast to establishing long-term connections or managing network traffic priorities, the principle of packet-switched networks focuses on the efficient delivery of packets rather than maintaining dedicated connections. While encryption is a critical aspect of data security, it is not a primary function of datagrams themselves. Datagram provides the framework for data to be encapsulated and transmitted, ensuring that it can navigate through complex network paths to reach its destination.
