physical connectivity of two devices. Some of the devices used in Physical layers are,
2. Data Link Layer – Data Link layer is responsible to transfer data hop by hop (i.e within same LAN, from one device to
another device) based on the MAC address. Some of the devices used in Data Link layer are,
3. Network Layer – The network layer is responsible for creating routing table, and based on routing table, forwarding of the input request. Some of the Devices used in Network Layer are,
Figure: Typical interconnection of Router, Switch, Hub and Bridge 4. Transport Layer – Transport layer is responsible for end-to-end communication (or process-to-process communication). Some of the transport layer devices are,
5. Application Layer – Application layer is the top most layer of TCP/IP Model that provides the interface between the applications and network. Application layer is used exchange messages. Some of the devices used in Application layer are,
What is an OSI device?The open systems interconnection (OSI) model is a conceptual model created by the International Organization for Standardization which enables diverse communication systems to communicate using standard protocols.
What are OSI Layer 2 devices?Layer 2 of the OSI model is known as the data link layer. The Layer 2 protocol you're likely most familiar with is Ethernet. Devices in an Ethernet network are identified by a MAC (media access control) address, which is generally hardcoded to a particular device and doesn't normally change.
What devices operate at OSI 1?Examples of layer 1 devices include hubs, repeaters & Ethernet cable connectors. These are the basic devices that are used at the physical layer to transmit data through a given physical medium which is suitable as per the network need.
Which device works at layer 3 of OSI model?Routers operate at this layer—sending data throughout the extended network and making the Internet possible.
