data link layer address

At which OSI layer is a destination IP address added to a PDU during the encapsulation process? Select one: MAC Address TCP Port Number IP Address Sequence Number Question 2 Which IEEE (802.x) wireless standard uses a point-to-multipoint topology to provide wireless broadband access? Data Link Layer. segments ; frames ; datagrams ; messages ; 5. This layer makes sure that the transfer of data takes place error-free from one node to another, over the physical layer. The data link layer adds _____ addresses to the frame to identify the sender and receiver. Data link layer is responsible for converting data stream to signals bit by bit and to send that over the underlying hardware. Network Layer and Data Link Layer Addresses • The network and data link layers are responsible for delivering the data from the source device to the destination device. • Protocols at both layers contain a source and destination address, but their addresses have different purposes. network layer data link layer application layer presentation layer 70. Data-link addresses sometimes are referred as physical or hardware addresses. The data link layer's first sublayer is the media access control (MAC) layer. The node to node delivery of a message is possible due to the data link layer. The IP address is a layer 3 (network layer) address. Answer : 1) link layer address : An Address which move frame from one point to another point in same network (LAN). In a network when a data packet arrives, the data link layer is responsible to transmit it to the host, using its MAC address. The MAC address is a layer 2 (data link) address. It pertains to … On the other hand, a data-link layer address uniquely identifies each physical network connection of a network device. The layer 3 address is a logical address. Data-link addresses usually exist within a flat address space and have a pre-established and typically fixed relationship to a specific device. Destination address, source address and MAC. A data link-layer address is the address of the physical address of the card or port, which connects to the network channel. Data link layer takes the packets from the Network Layer and encapsulates them into frames. The data link layer divides the stream of bits received from the network layer into data units called _____. Framing is done in Data-Link layer. logical ; port ; physical ; network ; 6. If two PCs in different networks, we try to sent data from one another, we specify the IP address of the destination PC in the Network layer for each packet. Example : MAC address, Ethernet address 2) data link con view the full answer At which OSI layer is a source IP address added to a PDU during the encapsulation process? network layer application layer transport layer presentation layer 71. What identifier is used at the data link layer to uniquely identify an Ethernet device? If the frame size becomes too large, then the packet may be divided into small sized frames. Data packets are framed and addressed by this layer, which has two sublayers. E.g In a LAN, the address of an ethernet card or MAC address is the address of the data link layer. The communication between the two data link layer uses source and destination data-link addresses. Data Link Layer Frame. At the receiving end, Data link layer picks up data from hardware which are in the form of electrical signals, assembles them in a recognizable frame format, and hands over to upper layer. We give physical addresses there. Physical Addressing: The Data Link layer adds a header to the frame in order to define physical address of the sender or receiver of the frame, if the frames are to be distributed to different systems on the network. The layer 2 address is a physical address. The data link layer is used for the encoding, decoding and logical organization of data bits. A frame is a unit of communication in the data link layer. It is used for source and destination addresses. This division of stream of bits is done by Data Link Layer. It will pertain to a single protocol (such as IP, IPX, or Appletalk).
