It also manages error notification, flow control and networktopologyThis OSI reference model layer also provides physical transmission of data by formattingmessages into small pieces, called data frames, and encapsulates the frames with additional datacontaining the hardware address of the destination device along with the information of thesource device. Every time a data packet is sent between devices, the data link layer frames it withcontrol information, so devices such as routers and gateways can properly forward the data to thecorrect device.Routers and switches also work at the data link layer to communicate and uniquely identifydevices that are connected to a local network. A typical Ethernet network uses MAC addressingto communicate with devices. Without the data link layer to frame data packets, data broadcastswithin a domain are prone to collision that could lead to network traffic congestion and lost datatransmissions.The data link layer resid
