datagram is used in conectionless n/w e.g. UDP Whereas packets used in connection oriented n/w e.g. ATM X.25 tcp
provides connectionless, unreliable serviceso UDP faster than TCPadds only checksum and process-to-process addressing to IPused for DNS and NFSused when socket is opened in datagram mode
Udp(user datagram protocol)
Datagram is UDP that is connectionless,best effort-delivery protocol which means it sends data and doesnot take responsibility for the data's integrity.But,it is useful when large number of data has to be sent. Kritika Raj
