WebIn the OSI model, the data link layer is a 4 th layer from the top and 2 nd layer from the bottom. The communication channel that connects the adjacent nodes is known as links, and in order to move the datagram from source to the destination, the datagram must be moved across an individual link. The main responsibility of the Data Link Layer is ... WebNov 11, 2024 · The datagram represents a data unit of transfer in networking. Data transmitted in a network is divided into smaller parts called datagrams. In a datagram, we divide data frequently and transmitted from source to destination without a predefined route. We also can’t guarantee the order of delivery to the receiver end.
