What else can I help you with?
Routers operate at layer LAN switches operate at layer Ethernet hubs operate at layer?
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
Switch work in which layer of osi model?
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Connectivity devices such as hubs and repeaters operate at which layer?
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
What devices operate only at the Physical layer of the OSI model?
All network devices have some component that operates at layer 1. Only hubs and repeaters operate entirely at layer 1.
Do connectivity devices such as hubs and repeaters operate at the Presentation layer of the OSI Model?
No. Only protocols that users can see on their screen are considered Presentation Layer based. Hubs and repeaters operate on the physical layer, because it doesn't do anything with the data, it simply forwards it.
What is the advantage of using switches rather than hubs?
The major benefit of a switch over a hub is the increase in the amount of collision domains. This allows a switched network to benefit from full duplex transmissions, negating the need for CSMA/CD, and doubling the potential throughput for each network segment. Switches typically operate at layer 2 of the OSI model, using destination MAC addresses within the Ethernet frame to intelligently filter or forward packets.
What layer do hubs operate at in the OSI model?
Its at Layer 1 of the Open Systems Interconnection Model (OSI model) Layer 7 Application Layer 6 Presentation Layer 5 Session Layer 4 Transport Layer 3 Network Layer 2 Data Link Layer 1 Physical
What distinguishes switches from repeating devices such as hubs?
layer 3 switches require ip address but hub do not require
What devices extend the size of a broadcast domain?
Layer 1 (hubs) or Layer 2 (bridges or switches) devices.
In which layer of osi model dose repeater works?
It depends on what kind of model it is, but in the model for computer 321O, it is on the layer between trhe keyboard and the behind screen, and there is a button with the osi code and there says everything.
Which of the following is considered a Layer 2 device?
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
Which two networking devices are used to connect hosts to the access layer?
Hubs and Switches
