A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm
A Switch is a Layer 2 device as they operate in the data link layer
the network layer is the same as the data link layer, they do the same thing. that is that they communicat with the network to send packets of data...
Physical, Data link and Network layers make the Network Support layers.
Definition of Hardware Specifications: The details of operation of cables, connectors, wireless radio transceivers, network interface cards and other hardware devices are generally a function of the physical layer (although also partially the data link layer; see below).Encoding and Signaling: The physical layer is responsible for various encoding and signaling functions that transform the data from bits that reside within a computer or other device into signals that can be sent over the network.Data Transmission and Reception: After encoding the data appropriately, the physical layer actually transmits the data, and of course, receives it. Note that this applies equally to wired and wireless networks, even if there is no tangible cable in a wireless network!Topology and Physical Network Design: The physical layer is also considered the domain of many hardware-related network design issues, such as LAN and WAN topology.
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
Router works in Network Layer of OSI model
No. Frames are used on the data-link (layer 2) layer. Packets are used at the Network (layer 3) layer.
network layer
When your on a wireless network nope :) When your off your wireless network Yes you are using your data usages!
Token ring local area network (LAN) technology is a protocol which resides at the data link layer (DLL) of the OSI model.
