The difference between Layer 2 and Layer 3 switching is the type of information inside the frame that is used to determine the correct output interface. With Layer 2 switching, frames are switched based on MAC address information. With Layer 3 switching, frames are switched based on network-layer information.
The answer choices are not provided for this question. Also this question was miscategorized it should be a networking question not science.
A layer 3 switch has routing capability like a router. However, it also has layer 2 switching capabilities like a switch. To fulfill both functions, layer 3 switches will generally have a greater number of ports than most routers.
A network device that forwards traffic based on layer 3 information at very high speeds. Traditionally, routers, which inspect layer 3, were considerably slower than layer 2 switches. In order to increase routing speeds, many "cut-through" techniques were used, which perform an "inspect the first packet at layer 3 and send the rest at layer 2" type of processing. Ipsilon's IP Switch and Cabletron's SecureFast switches were pioneers in cut-through switching.
It is a layer 3 switch
I believe it's a router. I have this question on a test the choices are. router, hub, layer 2 switch or firewall. I answered layer 2 switch. It was wrong.
I believe there is no such thing as switching "from layer 3 to layer 2". Switching is either done within layer 3, or within layer 2.
because one layer is the electrical part, and the other layer is the place where the switch is on.
A layer 2 switch uses the MAC address to determine which port to switch the frame out of.
Routers operate at layer 3 of the OSI model while switches operate at layer 2. The data transmission form of a router is called a packet while in a switch, it is called a frame. Routers are mainly used in wide area networks while switches are used in local area networks.
A Switch is a Layer 2 device as they operate in the data link layer
1)Hub is a layer 1(physical layer)device whereas switch is a layer 2(datalink) device. 2)Hub sends data to all ports unnecessarily.so in this way it shared bandwidth whereas switch sends data to exact that port which required it after learning destination MAC address.so here is a dedicate bandwidth.

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.
