The OSI model consists of the following layers 7. Application layer 6. Presentation layer 5. Session layer 4. Transport layer 3. Network layer 2. Data link layer 1. Physical layer These layers are bottom-up approach. 7. Application layer Application layer protocols have been developed for file transfer, e-mail, network management and other applications. 6. Presentation layer The presentation layer is responsible for presenting data in the format the user can understand.This layer is also known as translation layer as this layer as a data translator from the network. 5. Session layer The session layer allows application on two different computers to establish a session or logical connections. DNS-Domain Name System protocols NetBIOS-Network Basic Input/Output System protocols NFS-Network File System protocols 4. Transport layer The transport layer is responsible to ensure that data is sent reliable from the sending node to the destination node. Split it up into small units if need be, pass these to the network layer and ensure that all the pieces arrive correctly at the other end. 3. Network layer The network layer deals with routing strategies which are responsible for delivery of a packet from source to destination. 2.Data link layer The data link layer provides for the transfer of frames across a transmission link that directly connects two nodes. 1. Physical layer The physical layer deals with the transfer of bits over a communication chennel for example, copper wire pairs, coaxial cable, radio or optical fiber.
