Network + OSI model questions and answers 2023The OSI Layers 1) Application 2) Presentation 3) Session 4) Transport 5) Network 6) Data Link 7) Physical All People Seem To Need Data Processing Application Layer The seventh layer in the OSI model, enable software programs to negotiate their formatting, procedural, security, synchronization, and other requirements for the network. Presentation Layer the sixth layer of the OSI model, serve as translators between the application and the network, using a common language for different hosts and applications to exchange data. Session Layer the fifth OSI model layer, coordinate and maintain links between two devices for the duration of their communication. They also synchronize dialogue, determine whether communications have been cut off, and if so, figure out where to restart transmission. Transport Layer The fourth OSI model layer, oversees end-to-end data delivery. In the case of connection oriented protocols, this means data is delivered reliably. They verify that the data is received in the sequence in which it was sent. They are also are also responsible for flow control, segmentation, and reassembly of packets. connectionless protocols do not offer such guarantees. Network Layer The Third layer of the OSI model, manage logical addressing and determine routes based on addressing, patterns of usage, and availability. Routers belong on this layer because they use this information to intelligently direct data from sender to receiver.
