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,
Which device operates at all layers of the OSI model?A. The following network devices operate at all seven layers of the OSI model: network management stations (NMSs), gateways (not default gateways), servers and network hosts.
What are the applications of OSI model?The OSI model helps network device manufacturers and networking software vendors: Create devices and software that can communicate with products from any other vendor, allowing open interoperability. Define which parts of the network their products should work with.
