Which layer of osi model has the important role of providing error checking?
Data link Layer
What acronym is used to reference the data link sublayer that identifies the network layer protocol encapsulated in the frame?
LLC Logical Link Control
Which layer of the OSI model is primarily concerned with accessing the physical media and physical addressing?
Data Link
What are the 7 layer of network?
It's called the OSI Model... it has 7 layers. 1) Physical Layer 2) Data Link Layer 3) Network Layer 4) Transport Layer 5) Session Layer 6) Presentation Layer 7) Application 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 type of device is switch?
A Switch is a Layer 2 device as they operate in the data link layer
What is a logically defined device that operates at the Data Link layer to pass frames between nodes?
virtual switch
What layer of OSI model is switches on?
Switches are on the second layer of the OSI model (Data Link); they do filtering based on host MAC addresses. You may also see a third layer switch; they not only provide all switching capabilities but some layer three routing capabilities too.
Does a DSL operate at layer 3 of the osi model?
No. A digital subscriber line (DSL) operates at layer 2 or the Data-link layer.
What protocols operates in the network osi layer and is able to communicate with the transport osi layer and the data link layer?
TELNET
What layer of the OSI model is a Switch on?
It operates on the data link layer of the OSI model (level 2). The switch creates a separate collision domain for each port. Although some switches operate on level 3 of the model and are called multi-layer switches.
Frame Relay is an example of a protocol which operates at which OSI madel layer?
- data Link
Ethernet operates at which layers of the OSI model?
Physical and Data-link layers.Physical being layer 1 and Data-link being layer 2.
What layers of the OSI model does the NIC operate?
The NIC operates on Layer 2 (Data Link Layer) of the OSI Model.
What kind of device is a standard switch considered to be?
Data-link layer
What layer of the OSI model does a switch operate at?
Switches are commonly known as "Layer 2 (Data Link Layer)".3550 Switches: These switches are working under Layer 2 (Data Link Layer) and it is forward the packets through MAC Address, but if we convert these type of switches into Routers it will function in Layer 3 (Network Layer) of OSI model as it's forward the packets based on the IP addresses.2950 Switches: These switches are working under Layer 2 (Data Link Layer) of OSI model only and it is forward the packets through MAC Address.
Does switch works on data link layer?
Switch working in Data link layer of OSI Model which is working my MAC address it is sending receiving packets by Mac address which switch make mac tale in RAM to save all information.
