During encapsulation process what occurs at the data link layer?
The physical address is added
Is DSL a WAN data link encapsulation?
Frame relay and PPP is used with WAN encapsulation. Frame Relay most closely compares to the OSI data link layer (Layer 2). If you remember that the word "frame" describes the data link layer protocol data unit (PDU), it will be easy to remember that Frame Relay relates to OSI Layer 2. Like other data-link protocols, Frame Relay can be used to deliver packets (Layer 3 PDUs) between routers.
What are two primary responsiblity of ethernet mac sublayer?
No, frame delimiting is a primary responsibility of the Logical Link Control sublayer of the Data Link Layer.. Data link layer exists of 2 sublayers; Media Acces control Sublayer (MAC) & Logical Link Control sublayer (LLC)
What are the three primary functions provided by Layer 2 data encapsulation?
Primary functions provided by Layer 2 data encapsulation include data link layer addressing, and the detection of errors via cyclic redundancy check calculations. An additional function is delimiting groups of bits into frames.
What primary three functions does data link layer encapsulation provide?
* addressing * error detection * frame delimiting
Which data link layer encapsulation protocol is used by default for serial connections between two Cisco routers?
HDLC
Which layer of the OSI model encapsulates Network layer pockets?
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
What is contained in the trailer of a data-link frame?
The trailer protocol is a link-layer encapsulation method that rearranges the data contents of packets sent on the physical network. by : Umesh The trailer indicates where a frame ends. It, along with the header, encapsulates a packet, making it a frame. by: eSeriate
Bridge is used in which OSI layer?
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm
What are the steps of encapsulation?
Encapsulation is the process of adding header information to the layers' data "payload". As the "payload" is passed from one TCP/IP (or OSI) layer to the next, encapsulating layer information is wrapped around the data. So, for example, if the application layer produces a data payload for transmission, it encapsulates it with application-layers headers, which then gets passed to the presentation layer. The presentation layer does the same and so down the protocol stack before transmission across the physical media. At the destination, the process is reversed by way of de-encapsulation where the headers are stripped-off by each matching layer at the destination. 1. Application, Presentation and Session layers create data. {Encapsulation headers added by layers} 2. Transport layer coverts data into segments for transport across the network. {Encapsulation headers added by layer} 3. Network layer converts segments into packets (or Datagrams). {Encapsulation headers added by layer} 4. Data Link layer converts packets (and datagrams) into Frames and the Data Link header is added. {Encapsulation headers added by layer} 5. Physical - frames are converted into bits for transmission over the physical media.{Encapsulation headers added by layer}
What layer arrange signals into logical units of information called frame?
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.
What is network layer of osi reference model?
The network Card(NIC) is on Layer 2, but the connector on the NIC is considered Layer 1 because the connector is considered a physical connection. Layer 1 ------Physical Layer 2 ------Data According to Network+ the answer is Physical.
