Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
Routers operate at layer 3. LAN switches operate at layer 2. Ethernet hubs operate at layer 1.
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first 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.
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.
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
layer 3 switches require ip address but hub do not require
Layer 1 (hubs) or Layer 2 (bridges or switches) devices.
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.
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.
Hubs and Switches
The physical layer is layer 1. It comprises the hardware (routers, repeaters, hubs, switches, etc.) that are used to form the physical basis of a network. They receive, process, and transmit raw electric (or optical) signals, rather than logical data packets.
