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.
What is an Ethernet switch and where does it fit into the OSI model?
Ethernet switch fits on osi physical layer
Which of the following OSI layers does a Layer 3 switch operate at?
network layer
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.
What information in an Ethernet frame is used by a Layer 2 switch to build its address table?
Source MAC-address
Which feature is uniquely found in an access layer switch within a hierarchical network model?
Power over Ethernet
Why switch is data link layer?
Data link layer refers to things that happen within a single network; that's what a switch does. Only a router (or equivalent device, which I would still consider a "router") is able to connect different networks.The different networks may use the same technology (for example, Ethernet and Ethernet), or different technologies (for example, Ethernet and Wi-Fi); a switch is only able to connect parts of a single network that use the same technology (often this will be Ethernet).
What type of device is switch?
A Switch is a Layer 2 device as they operate in the data link layer
What is layer 2 switching?
This refers to switching at layer 2 of the OSI reference model, for example, Ethernet. A switch looks at the MAC address of each Ethernet frame ("packet", you might say, but at this level the correct name is "frame"), and if it knows that this MAC address is connected at a certain port, the switch will send the information out ONLY through that port.This refers to switching at layer 2 of the OSI reference model, for example, Ethernet.

What devices operate at the session layer of OSI model?
Gateway network device
Where is a MAC address stored in a Switch?
Switches store the MAC addresses in an internal database called MAC Address Table. The entries in that table can be addresses learned by the switch or that can be entered manually by the switch administrator. This table is analogy to a router's routing table, only a switch operates at layer 2 whereas the router operate at Layer 3.
Where does Ethernet protocol align in the osi model?
Ethernet is a data link layer protocol - layer 2
