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.

Is vsat layer 2 or layer 3 device?
VSAT is a layer 2 device.
How does information get passed from one layers to the next in the internet model?
Each layer in the sending device adds its own information to the message it receives from the above layer and sends it to the layer below it. At layer 1 the entire package is converted to a form to be transmitted to the receiving device. On the receiving device side, the package is unwrapped layer to layer. Each layer removes data meaningful to it and sends the rest to the above layer and so on. Hope this was helpful By nour el houda
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames 2.dividing the application data into segments?
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames? Data link layer Which of the OSI layers handle the following: 2.dividing the application data into segments? Transport layer the PDU (Packet Data unit) for layers is as the following - Application, Presentation, and Session layers ==> uses Data - Transport layer ==> uses Segment - Network layer ==> uses Packets - Data link layer ==> uses Frames - Physical layer ==> uses Bits. ....
Router is a layer 3 or 4 device if your ans is layer 3 then while applying an extended access list on router interface how specifying port no is aloud as it comes under layer 4 protocols?
A router is a layer 3 device.In general, a Layer-3 switch (routing switch) is primarily a switch (a Layer-2 device) that has been enhanced or taught some routing (Layer 3) capabilities. A router is a Layer-3 device that simply do routing only. In the case of a switching router, it is primarily a router that may use switching technology (high-speed ASICs) for speed and performance (as well as also supporting Layer-2 bridging functions). As illustration, here are some examples Layer-2 switches Cisco: Catalyst 2950, 2960 series Layer-3 switches or routing switches Cisco: Catalyst 3550, 3560, 3750, 4500, 6500 series Juniper: EX series Routers (with some bridging and/or security features) or switching routers Cisco: 1800, 1900, 2600, 2800, 2900, 3700, 3800, 3900, 7200, 7600, ASR 1000 series Juniper: MX series, J series, M series
What layer of the OSI model performs error correction?
Layer 2 - The Data Link Layer Layer 2 of the OSI model provides error-detection capability
Is vsat layer 2 or layer 3 device?
VSAT is a layer 2 device.
Which layer of the OSI model includes the MAC address?
That is considered part of layer 2.That is considered part of layer 2.That is considered part of layer 2.That is considered part of layer 2.
What type of device is switch?
A Switch is a Layer 2 device as they operate in the data link layer
Which are layer 1 switches?
There are no layer 1 switches; switches run at layer 2 or 3. A hub is a layer 1 device.
Why is a switch called as layer 2 device?
because one layer is the electrical part, and the other layer is the place where the switch is on.
Does MAC address operates at Layer 2?
yes. thougth the nic is a layer 1 device its mac address is used in datalink layer
What device do you need to connect 2 VLANs?
A layer 3 switch or a router.
Which device should be included in the network topology to provide Layer 2?
hub
Switches operate at layer and Hubs operate at layer of OSI model?
Hubs are a physical layer (layer 1) device; most switches operate at the Data Link layer (Layer 2) of the OSI model.
What is a switch known as that operates on layer 7?
There are no switches that operate on layer 7 (Application layer) on the OSI Model. Switches are a layer-2 device because they manage and switch frames.
Which device connects network segments at layer 2 of the OSI model?
Bridge
Which devices work in the presentation layer?
firewall, router,layer 3 switches and i approve that answer ! NO! In general the firewall is a layer 4 device, it traffics filter incoming and outgoing ports. It uses the function of TCP and UCP. However a Firewall can also be a layer 3 device as in internal firewall in a router. Also a switch is a layer 2 device unless your talking about a Router switch.
