Question

In Networking, you are working on the various layers of an OSI model. Now, which of the following represent the functions of a Data Link Layer (DLL): 1. Logical addressing 2. Framing 3. Error control 4. Access control 5. Routing 6. Flow control 7. Physical addressing​

Answer 1

option 4

function of data link layer

framing,

error control,

access control,

flow control and

physical address

Answer 2

Data Link Layer in OSI model:

In the OSI model, the data link layer is the second layer and it is used to transfer a message from one node to another node. if it receives the packet or message from the physical layer then the data link layer transforms a packet or message to the host using a MAC address.

The functions of the Data Link layer is:

1. Framing

2. Physical Addressing

3. Error control

4. Flow control

5. Access control

In the given options, the routing and logical addressing are the functions of the Network Layer.
