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 else can I help you with?
What type of device is switch?
A Switch is a Layer 2 device as they operate in the data link layer
What kind of device is a standard switch considered to be?
Data-link layer
Does switch works on data link layer?
Switch working in Data link layer of OSI Model which is working my MAC address it is sending receiving packets by Mac address which switch make mac tale in RAM to save all information.
Switch work in which layer of osi model?
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
Bridge is used in which OSI layer?
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm
What layer of OSI model is switches on?
Switches are on the second layer of the OSI model (Data Link); they do filtering based on host MAC addresses. You may also see a third layer switch; they not only provide all switching capabilities but some layer three routing capabilities too.
What layer of the OSI model does a switch operate at?
Switches are commonly known as "Layer 2 (Data Link Layer)".3550 Switches: These switches are working under Layer 2 (Data Link Layer) and it is forward the packets through MAC Address, but if we convert these type of switches into Routers it will function in Layer 3 (Network Layer) of OSI model as it's forward the packets based on the IP addresses.2950 Switches: These switches are working under Layer 2 (Data Link Layer) of OSI model only and it is forward the packets through MAC Address.
Which layers does a link-layer switch process?
The link layer...
Bits are packaged into frames at which layer of the OSI model?
Data link layer
What is a logically defined device that operates at the Data Link layer to pass frames between nodes?
virtual switch
Which layer is represented by frames?
The data link layer (layer 2) and the physical layer (layer 1) use the constructed frame.
Discuss allthe network devices used indifferent layer oftheosi model?
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
