A datagram is a basic unit of data used in networking, particularly in connectionless communication protocols such as UDP (User Datagram Protocol). Its primary purpose is to facilitate the transport of data packets over a network. A datagram contains not only the data being sent but also the necessary header information, which includes source and destination addresses, and other control information that ensures proper routing and delivery.

This specific structure enables efficient communication over networks, where the emphasis is on delivering messages without the overhead of establishing a dedicated connection, which is typical in connection-oriented protocols. By encapsulating the data within a single package that can be sent independently, datagrams support efficient data transfer and can navigate diverse networking environments.
