Question

The OSI Data Link Layer true true true true false - adds a header and tail to the message from the network layer false - maintains connections between nodes on different networks false - considers IP addresses as MAC addresses false - may need to synchronize frames transmitted Record Answer

Answer 1

The data link layer ensures that all packets of information are passed on free of errors. It makes sure the appropriate physical protocol is assigned to the data. The data link layer is the second layer in the OSI Model. The three main functions of the data link layer are to deal with transmission errors, regulate the flow of data, and provide a well-defined interface to the network layer. When it transfers the data to the network layer, it uses timers and sequence numbers to check for errors to ensure that all data is successfully received. The data link layer has different services and protocols to complete its tasks. The protocols are the rules required to pass data successfully to the next layer. Ans: adds header and tail to the message from the network layer: true maintains connections between nodes of different networks: false (data link layer can communicates in same network) considers IP addresses as MAC address: False may need to synchronize frames transmitted: True
