What is the use of data-gram encapsulation?

Datagram encapsulation is used to package data into discrete units called datagrams for transmission over a network. This process involves adding headers and trailers to the data, which contain essential information such as source and destination addresses, protocol type, and error-checking information. By encapsulating data into datagrams, it ensures efficient routing, delivery, and error handling across different network layers. This approach is fundamental in protocols like UDP (User Datagram Protocol), which prioritize speed and simplicity over reliability.
