data link layer should divide frame into segment by ravi from kurnool
Frames are encapsulating packets. The data link layer makes framing and provide this service to the layer above layer "the network layer".
The PDU at the Network layer is referred to as a packet. A PDU at the Data Link Layer is referred to as a frame.
to convert a frame into a series of signals to be transmitted on the local media
Layer 2 or the 'Data' layer of the OSI model encapsulates either 'bits' from the physical layer (1)- moving up the TCP stack or 'Packets' from the Network layer (3)- going down the the stack. 7 - Application Layer DATA 6 - Presentation Layer DATA 5 - Session Layer DATA 4 - Transport Layer SEGMENT 3 - Network Layer PACKET 2 - Data Layer (Incorporating LLC and MAC) FRAME 1 - Physical Layer BIT A good nmemonic for remembering the data encapsulation in the OSI model is 'Don't Some Peolple Fry Bacon' - Data, Segments, Packets, Bits.
Layer 2 - Data Link layer.
It depends on which textbook you are reading; some textbooks state that the frame is constructed in the data link layer (layer 2) and transmitted out the physical layer as a packet. Some other textbooks will say that the packet is created in layer 2 and transmitted out the physical layer as a frame.

No. Frame Relay is not operating at Layer 3. Frame Relay is strictly a Layer 2 protocol suite, whereas X.25 provides services at Layer 3 (the network layer) as well. This enables Frame Relay to offer higher performance and greater transmission efficiency.

yes,data link layer finalize and frame a packet as frame is a series of bits that units a data.........

A PDU (Protocol Data Unit) is defined by which layer it is in. In the physical layer and network layer, it is synonymous with the packet, in the data link layer, it is the frame. In the transport layer, it is a datagram for UDP. A datagram holds one or more PDU's, as it is the basic unit of transferring information via packet switching.
layer 2
A basic ozone layer is a pool of ozone molecules. They absorb the UV.
The data link layer (layer 2) and the physical layer (layer 1) use the constructed frame.
