What are the sublayers of the Data Link layer are as defined in the IEEE 802 standards?
Logical link control sublayer and media access control sublayer
What else can I help you with?
IEEE has divided the Transport layer into two sublayers?
No. It is the Data Link layer that IEEE has divided into two sublayers. The Data Link layers are Logical Link Control and Media Access Control.
Which standard divides the data link layer into the LLC and the MAC sublayers?
802.2
Where do the MAC sublayers fit into the OSI model?
MAC sublayer is located at Data link layer.
Hardware addresses are defined at this layer?
They are defined in the OSI layer known as Data-Link.
Why Bridges operate at Layer 2?
Layer 2 of the OSI model, the Data Link Layer is composed of two sublayers, the lower being the MAC layer that regulates how computers access information on a network and transmit it. A bridge connects two networks, or two sections of a LAN, and works at the Data Link Layer to regulate it.
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 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 layer is divided into two layers?
The OSI model's data link layer is divided into two sublayers: the Logical Link Control (LLC) and the Media Access Control (MAC) layers. The LLC layer manages communication between devices on a network, while the MAC layer controls access to the physical network medium.
What is a logically defined device that operates at the Data Link layer to pass frames between nodes?
virtual switch
What are the main functions of each layer of OSI model?
layer 7- Application layer layer 6- Presentation layer layer 5- Session layer layer 4-Transport layer layer 3-Network layer layer 2- Data Link layer layer 1- Physical layer
Explain the difference between a PDU and a datagram?
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.
What is the PDU at each layer?
Application layer: Data Presentation layer: Data Session layer: Data Transport layer: Segment (TCP) or Datagram (UDP) Network layer: Packet Data Link layer: Frame Physical layer: Bit
